Thomas the Tank Engine works at the Big Station, fetching coaches for the bigger engines. He keeps teasing Gordon the Big Engine, making him very cross. When the Shunter later accidentally forgets to uncouple Thomas from Gordon's coaches, Gordon decides to be really fast to tire Thomas out.

Edward is feeling sad, as all the other engines are bigger and younger than him. But when Gordon gets stuck whilst pulling trucks up a hill, it's Edward to the rescue.

Henry the Green Engine doesn't like getting his paint wet - so refuses to come out of the tunnel. The Fat Controller tries everything, including getting Thomas to push Henry out but the big green engine still does not move. In the end, the Fat Controller orders a brick wall be built to block the tunnel entrance, meaning Henry stays in the tunnel forever...

Henry is sad that he is stuck in the tunnel, and Gordon is having fun teasing him whenever he passes. One day Gordon's safety valve bursts just outside the tunnel. Edward is the only other engine available, but the train is too heavy for him. How could the situation possibly be resolved?

Thomas wants to pull a train instead of just shunting coaches for the big engines, who laugh and say he wouldn't be able to do it. One night Henry is ill, and next morning he still isn't better. He is due to pull the morning train, and when no other engine is available, Thomas has to pull the train. He is so excited, he doesn't notice until too late that he has started before being coupled to the train, leaving his coaches and passengers left stranded at the platform!

Thomas is bored, and when one night Edward offers to swap duties with him for the next day, Thomas takes up the offer. This involves taking Edward's trucks. However Thomas is not used to trucks...

Thomas is in the yard shunting when new engine James rushes past with a goods train yelling for help. James has wooden brakes and the trucks are pushing him down the line. The alarm goes - James has crashed into a field of cows. Thomas has to get the Breakdown Train and help James. Afterwards, the Fat Controller gives Thomas a very special reward.

James the new engine has to pull some coaches with the help of Edward. They do very well but James is so excited that he accidentally showers water all over the Fat Controller's new top hat! Later on he is pulling more coaches and bumps them so hard that a brake pipe is damaged. Newspaper and a leather bootlace could temporarily mend the problem, but only a passenger willing enough to hand over their laces will the train be able to continue...

James is feeling sad as he is still staying in his shed for being naughty. Eventually the Fat Controller lets him out to pull a goods train, but the trucks don't want to be pulled by James and misbehave. Whilst pulling them up Gordon's Hill, a coupling breaks and the last few trucks roll back down the hill. James goes to get them (they were stopped by the Guard) and starts on up the hill once more...

Gordon boasts to James that he is the only engine who can pull the Express. One day he sets off with it, but due to points problems he comes back to the station feeling very sheepish. Another engine will now have to take over the job of pulling the Express for the day, but who will it be?

One day Thomas is late with his train due to Henry being late at the Junction, and when the Guard blows his whistle Thomas zooms off - without giving the Guard enough time to get on the train! Annie & Clarabel try to stop him, but Thomas continues to steam on!

Thomas has a desire to fish, and the others tell him "Engines don't fish!" When the water tower is out of order, Thomas has to take water from the river via a bucket. When suddenly he feels like he's going to burst, the Driver and Fireman look inside his tank and discover something rather unusual...

In Autumn, Thomas stops by a signal. There he meets Terence the Tractor, and teases him about his caterpillar tracks. When winter comes, so does the snow. Thomas refuses to wear his snowplough, and when he does he breaks it. Due to this he ends up getting stuck in the snow...

Bertie the Bus challenges Thomas to a race, to see who can get to the end of the line first. Thomas faces obstacles such as stations, signals and a slow start, Bertie has bus stops and traffic lights - who will win?

Gordon has to pull his train backwards due not trying hard enough to move into the correct position on the turntable, so as to be turned around. And when James gets on the turntable, the strong sea winds spin it round much too fast. The two, plus Henry, are very cross about the the unfortunate events that happened to them and so all formulate on a plan...

Henry, Gordon and James decide to go on strike, declaring that "Tender Engines don't shunt!" The Fat Controller sends Edward to do the work; but when poor Edward is being teased, the Fat Controller then decides to buy a new tank engine called Percy.

After being shut up for days in the shed, Henry, Gordon and James have been let out to work again. So the Fat Controller sends Thomas, Edward and Percy to play on the Branch Line. But Percy, however, becomes a little too cocky for his own good and suddenly finds himself on the Main Line - and on a collision course with Gordon...

Henry keeps feeling ill, unlike the other engines. It turns out that Henry's firebox is much smaller than the other engines', so the Fat Controller orders special Welsh coal that will allow Henry to work better. The Green Engine is thrilled with the results.

One winter's evening, Henry is excited to be given the chance to pull the fish train that the men call, "The Flying Kipper". Unfortunately, snow and ice result in an accident. The Fat Controller decides to send Henry off to the Works at Crewe, where Henry will unknowingly be given more than just a repair job...

Gordon becomes a little too above himself but learns a lesson when his whistle valve comes out of place causing quite a noise!

Meanwhile, some boys also soon learn a lesson after throwing stones at Henry and his coaches from an overhead bridge.

We meet Toby the Tram Engine and his coach Henrietta, who both work hard on their little line. One day, a stout gentleman (the Fat Controller), his wife and grandchildren, Stephen and Bridget, come to visit and become very fond of Toby. Some months later, the line is sadly closed, but little does Toby know he has been saved by a letter from a certain personage...

There is a Quarry at the end of Thomas's Branch Line, and he has to take the trucks to and from it. One day a new Policeman starts work and tells Thomas off because he has no cowcatchers and sideplates. It turns out this is the Law, so the Fat Controller will have to build them for Thomas. Thomas says he will look like a tram. But rather than give Thomas a tram overhaul, a much better idea has come into the Fat Controller's mind...

Toby and Henrietta are old and shabby looking. James remarks about how dirty they are, and says how he'd never be seen looking like that. James then has to pull a goods train along Gordon's Hill, but the trucks push him down and up ahead, a train of Tar Wagons lies...

It's Christmas on the Island of Sodor, and after Edward reminds the engines of last Christmas when an ill Mrs Kyndley waved her dressing gown out of her window to save Thomas from a landslide, Thomas decides to thank Mrs Kyndley properly by having a Christmas party for her. The Fat Controller agrees. However, on the day of the party, Mrs Kyndley is trapped in her house by snowdrifts, so Thomas, Toby and Terence go to her rescue.

One day, Gordon is dozing in a siding when Henry comes by, waking him up with a loud whistle or two! Gordon tells Henry, "Mind you keep on the rails today," in regard to his previous incident with the Flying Kipper. Not long afterwards, Gordon feels most annoyed when he is asked to pull a goods train. So whilst on the turntable, he tries a bit of sabotage - which doesn't go according to plan...

Gordon is in disgrace after falling in the ditch. Thomas teases him about it, saying he has, "A funny, musty, sort of smell!"Later, Thomas has to deliver trucks to an old Lead Mine. The ground beneath the rails running overhead is weak and whilst it can support the weight of trucks, it can't support the weight of an engine. But Thomas ingnores the "Danger" signs.

Thomas boasts of how his blue paintwork looks splendid. But he doesn't look so splendid when he gets covered in coal dust whilst working at the Coal Hopper! Percy laughs at his friend's accident, but it's not long before he has a mishap with coal too!

Old Edward unknowingly loses part of his train due some bothersome cows who break out of their field and cause a coupling to come loose. He feels very cross when Henry and Gordon laugh about it and boast that cows wouldn't bother them. However, they'd reckoned without Bluebell the cow!

It's not a good day. Thomas's fireman doesn't come into work, which means that Thomas can't deliver his passengers, which means that he can't make his connection with Edward, which means that this makes everyone late and cross. Bertie offers to take Thomas's passengers; but he has a field day of it when Edward, tired of waiting, steams away. The chase is on!

In a lonely, rusty Scrapyard is poor Trevor the Traction Engine, who is ready to be broken up. He is feeling sorry for himself because he feels that he's too old-fashioned to be Useful. Edward finds Trevor's situation to be a tremendous shame, and is determined to find someone to buy Trevor and save him, but who would "have room for a Traction Engine at home?"

Some boys fiddle with James's controls and he trundles off down the line by himself. It is up to Edward to catch up with James and allow James's fireman to jump aboard the runaway engine to stop him.

Trevor is getting bored, but Edward has good news. The Fat Controller wants Trevor to help with his new Harbour. Edward takes Trevor to the Junction, where the Traction Engine meets Thomas. Thomas takes him down to the Harbour, but has his doubts as to how useful Trevor can be since he doesn't run on rails. Thomas is soon pleasantly surprised.

Percy has been playing tricks on the bigger engines, such as telling Gordon he is late for his train and telling James he mustn't leave the shed because an Inspector is coming to visit. Gordon and James want their revenge, and so come up with a plan to trick Percy, by brainwashing him with the ludicrous idea of "backing signals"...

Percy is ill of the bigger engines around ordering him about. The Fat Controller releases him to work at his new Harbour, and also brings in a new engine called Montague, but who prefers the name of "Duck". The big engines try and order Duck around as well, but Duck won't stand for it and together with Percy, he puts them in their place.

Percy is enjoying his new work at the Harbour. The line is near an airfield, where a boastful helicopter called Harold lives. He reckons that, "Railways are slow and quite out of date!" But Percy proves a point when he challenges Harold to a race...

Thomas is feeling unwell, so Edward takes him to the Works to be repaired. Whilst Thomas is away, Duck fills in for him and is very popular with Annie, Clarabel and the passengers. When Thomas comes back, he resumes his duties. However his handbrake hasn't been fixed properly by the workmen and one day the Fireman forgets to pull it hard enough. As a result, Thomas and the coaches "run away", and only Harold and an Inspector can help stop the runaway train.

Percy brags that "Water is nothing to an engine with determination!" But he feels very foolish when he learns that you can't trust trucks and takes an unfortunate dip!

Duck is boasting about being Great Western and how useful he is, much to the annoyance of the others. Later, the Fat Controller introduces Diesel, a shunter who is "on trial". He asks Duck to show Diesel around, but Diesel says he doesn't need Duck. Duck leaves him to it and Diesel has an accident with some trucks. He thinks it's Duck's fault...

Diesel is still angry at Duck, and plans his revenge. He tells the trucks jokes about Gordon, James and Henry, and says Duck told them to him. The trucks start gossiping, and soon enough the big engines find out...

Duck has been sent to work with Edward for a while, and tells Edward that the Fat Controller and the other engines all hate him. Edward says they don't, and asks Duck if he would like to help him work. Duck helps Edward pull a heavy goods train up Gordon's Hill, but the trucks break away and speed down the line. Duck manages to control them but a barber's shop is up ahead...

The viaduct is being repaired on the Main Line. The Fat Controller doesn't want to close the railway whilst the repairs are being done, and so orders the mainliners to go slowly when crossing it. This delays them with their journey to Thomas, which makes him late to meet with Bertie. Altogether, Thomas becomes very annoyed; until the day comes when he realises that being late isn't such a bad thing after all.

Donald & Douglas have arrived from Scotland to help the Fat Controller - but have caused great confusion in that only one engine was expected! Despite all, they try their best but a spiteful brake van causes trouble between them.

The engines are worried that Donald & Douglas might be sent away after their accidents. Edward suggests that they hold a Deputation - and poor Percy gets the task to tell the Fat Controller about it!

For many years, Thomas the Tank Engine has run his well-known branch line, and knows just where to stop. "You could almost manage it without me!" jokes his Driver. What a surprise Thomas gets when he tries to do so and pays the Stationmaster an unexpected visit!

Thomas's recent accident has caused a great deal of trouble. The Fat Controller decides to send for a Diesel Railcar called Daisy to help Percy and Toby "while Thomas is... ummm... indisposed!" But poor Percy and Toby have a hard time when Daisy becomes difficult and bitter.

Percy grumbles about taking the milk when Daisy doesn't bother to do so. Toby offers him to swap jobs; he takes the milk and Percy fetches his trucks. However, Percy becomes rather cocky and soon finds himself in trouble with runaway trucks and a breakvan in the way...

Bill & Ben are twins who work at the China Clay Pits. One day, they are aghast when they discover that their trucks have gone missing! Down the line, they cause great problems and difficulty with a diesel called Boco, who they believe stole the trucks. Confusion regains until Edward explains everything.

Since the arrival of Boco, Gordon is upset when the Fat Controller allows branch line diesels to pull main line trains. Edward suggests that he should run on the branch for a change. Gordon thinks such an idea "vulgar", but little does he know that a run on the branch is quite unexpectedly in store that night...

Henry, Gordon and James are teasing poor Edward about being too old and "how he should be preserved before it's too late." Duck and Boco tell them to "Shut up!" as "Edward's better than any of you!"; and during a serious breakdown on an important journey, Edward proves his worth once and for all.

Percy tells Thomas and Toby a story about a ghost train. Thomas doesn't believe it and says Percy is a "silly little engine". Percy's Driver later tells him it wasn't true, it was on television. Later that night, Percy is on his way back from the Harbour when he crashes into a lime cart trapped on a crossing. Now white as a sheet, and with help from Toby, Percy heads off to find and scare Thomas...

During the summer, Percy likes to help the harvesters by delivering their bales of hay to Toby, who takes them to the farms, to feed the animals. Unfortunately, Percy makes Thomas very late and cross indeed. Percy doesn't care until a crate of treacle and a hay storm cause some embarrassment...

The Fat Controller sends Thomas to fetch the Christmas Tree for the Christmas party, but on the way back he gets stuck under a big snowdrift. No-one knows what has happened to Thomas, so Donald & Douglas go out to look for him. Will Thomas get home in time?

The Island of Sodor is in the grips of winter. Percy, complaining about his funnel being cold, wishes for a long, woolly scarf to keep it warm. He soon knows why engines never wear scarfs when he has a surprise collision with a baggage trolley...

It's holiday time and the Vicar's Sunday School is spending the day at the seaside. Percy promises Thomas that he'll get Annie, Clarabel and the children home safe and sound; but floods spell disaster for the little engine until...

The Fat Controller feels that Gordon is being worked too hard and so decides to give him a rest and let James take his place for a while: This makes James feel proud and boastful. However, his bragging soon fades when he has an unexpected run in with Toby, who has run out of water on the Main Line.

Everyone is excited at the arrival of the celebrity engine, 'City Of Truro' - all except Gordon, who sniffs at the fact that C.O.T. is a "domeless engine". However, when trying to break C.O.T.'s world record, he receives total humiliation thanks to a teasing wind.

As a reward for his hard work, Duck is given his own branch line; he starts boasting endlessly about it and Donald teases his that he quacks "as if he laid an egg!" So Duck's driver and fireman decide to play a trick on Donald - with "quacking" results!

After helping some children out of a sticky predicament, Thomas gets behind his timetable and is very late. Then things go from bad to worse when his Branch Line gets damaged by hot weather and has to be closed whilst it is being repaired. Bertie the Bus offers to takes Thomas's passengers while he shunts in the yard; and this makes the little engine worry that his passengers will forget about him.

Percy teases Thomas about the time that he got scared in "Ghost Train". But one afternoon, Percy gets stuck in a siding after a points failure and has to spend the night there, where he encounters a terrifying dragon! But will anyone believe him?

Duck and Percy are exhausted with the extra work in the harbour so the Fat Controller sends for another engine to help them. What a shock they receive when it turns out to be Diesel!

Henry's favourite place on Sodor is the forest; he loves the trees, the animals and the peaceful nature sounds. He is heartbroken when storms damage the trees and the broken timber gets cut up and turned into furniture. Luckily, help is at hand...

Gordon is smothered in mud, but refuses to be cleaned. So the Fat Controller, as punishment for disobeying orders, orders him to pull trucks, whilst James looks after the Express. But in the end, after Gordon helps James, he learns that "Having a wash down is essential to every engine."

When Gordon annoys James by saying he's not as important as him, James decides to get revenge by telling Thomas that the Fat Controller wants James to pull the express and that Gordon should pull the trucks. Confusion ensues...

Thomas and Percy pull the Post Train most nights. When the trains start to run late though, the future of the Post Train is put in jeopardy as the Post Office decide to start using Harold instead. Luckily a special passenger - and some strong winds - save the day.

James is groaning because he has to deliver trucks to the quarry. Gordon tells him that he should pretend to be ill so he doesn't have to do the job. Thomas soon pulls in and offers to deliver the trucks instead and so the two big engines slyly agree. Later, Thomas unfortunately doesn't realise that trouble is ahead just down the line and he wouldn't have been put in such a situation if it weren't for Gordon and James...

Mavis is a young diesel engine who is starting work at the quarry. Unfortunately her way of shunting is a lot different from Toby's and he gets annoyed. A bit of false encouragement from Diesel gets Mavis into trouble.

Mavis is told that she is not allowed anywhere near Toby's line, so when the trains get bigger she develops a plan for the trucks to push her there. But Toby accidentally takes those trucks and they decide to push him instead. As Toby speeds down the line, he realises that the bridge ahead is collapsing and he knows that he can't stop in time!

The Vicar is having a garden party so that he can raise money for a seaside trip for the children. Trevor is the star attraction, but Edward wishes he had something to do to help out too. In the end he helps the vicar with the posters advertising the party.

Meanwhile, Bertie is teasing Trevor about being old, but Trevor has the last laugh when Bertie gets into a sticky situation.

James is chatting to Trevor about some bees who Trevor is looking after. Boco warns them to not to annoy the bees, which annoys James. The next day, some bees escape from the station and cling onto James's warm boiler... and refuse to let go!

Duck wishes he could sail to far away lands but Percy tells Duck he'd rather stay on his dry rails. So, when Duck helps Harold out in an emergency situation, he decides that Percy is right and that he would be much happier on his own rails.

Bill and Ben are sent to the big yard by the Fat Controller to help the other engines with important goods. They work well but when it comes to going onto a turntable for the first time, things get out of hand.

The Fat Controller invites a visitor to Sodor - an engine with 2 tenders! Henry gets jealous of this and thinks he should have more tenders. Duck offers to give Henry his tenders - but they don't quite turn out to be what Henry expected...

Douglas attempts to rescue a frightened engine called Oliver, and his brakevan, Toad, from the place all steam engines fear to go - THE OTHER RAILWAY!

The story about Oliver's rescue soon goes around the island, and the other engines compliment Oliver about how clever he is. This gets him rather big-headed until the trucks teach him a lesson...

A doubledecker bus called Bulgy thinks he knows a shortcut to get to the Big Station quicker but doesn't go far when he ends up becoming stuck beneath a rail bridge.

At the docks, the Troublesome Trucks play tricks on and confuse Bill & Ben which makes them late to deliver the coaches for Gordon's Express, making him very late indeed.

The next day, a rockslide threatens the quarry and only Bill & Ben are the ones who can save the workmen in danger...

Percy and James soon learn that pride comes before a fall when they have a rather bad day that involves fruit.

It's Christmas time on the Island of Sodor and Thomas is looking forward to delivering letters and parcels to his friends in the towns and villages. But it's been snowing again and one of the villages has been snowed up. It's up to Thomas, Percy, Harold and Terence to help save the day!

The engines are having trouble getting to sleep, so Thomas tells them the story of Duke... Duke, Stuart and Falcon worked on their own little railway years ago, until hard times came forcing the line to be shut down. Stuart and Falcon are bought by other people but Duke is left alone in the shed...

Thomas tells the engines the rest of his story about Duke and how a group of people set out to save him.

Percy is feeling rather annoyed because he has a new coat of paint and is longing for everyone and anyone to see it. So Thomas tells him the following story...

Before the problems come to their railway, Falcon is doing rather well, and the manager explains to him that he is now ready to take on "The Mountain Road", a difficult part of the line, so Duke is coming along to help. Falcon is not happy about this.

Falcon and Duke set off, but Falcon becomes careless and finds himself hanging on the edge of the hillside...

Stuart is being rather cheeky to Duke about his old age but is taught a lesson later on that day thanks to a clever plan...

Skarloey feels lonely when Rheneas goes away to be mended; he wishes he could be young and pull coaches again. He finally gets his chance when some stubborn coaches damage Sir Handel and he offers to take over. But he soon realizes that he is not as young as he used to be...

Skarloey and Rheneas are two old engines, who tire very easily. So the Manager sends for Sir Handel and Peter Sam to help them; but Sir Handel is cross and rude and gets himself into trouble...

Whilst Sir Handel is shut up in the shed, Peter Sam is doing his work as well as his own - and does he love it! However, Henry says that if he is late, he'll leave his passengers behind; this makes Peter Sam worried and impatient and causes him to almost leave a passenger behind...

Trucks - Sir Handel doesn't like them and they don't like him. So, after some 'helpful' tips from Gordon, he tricks Peter Sam into doing his work which leads to a great dilemma...

Peter Sam is delighted when Skarloey returns home. He tells him about Duncan, who came as a spare engine after his accident.

Skarloey would like to meet Duncan but gets to sooner than he expected!

Rusty and the men are working hard to mend the line; but there is still one bad bit, before the first station, which they haven't had time for. The little diesel tells Duncan to be careful. But Duncan doesn't like being told what to do, and so he rocks 'n' rolls along the line...with predictable results!

Ever since his accident with the trucks, Peter Sam's funnel is constantly wobbling and clanking as the winter wind ties to blow it away. When the snow and frost comes, an icicle in a tunnel brings disaster for the poor engine; until the Fat Controller presents him with a new special funnel...

Sir Handel brags about his "steamroller wheels" and boasts that he can go faster than the other engines. Tired of this, Skarloey tricks him into having a race with George, the grumpy steamroller.

Skarloey is delighted to hear the news that Rheneas is coming home from the menders. Nancy, the guard's daughter, is planning a 'welcome home' party for him; and because of this, she hasn't had time to polish Duncan. This makes Duncan very cross indeed and causes a great deal of trouble...

Duncan is still complaining about passengers being a nuisance. But Skarloey tells him just how important passengers are, when he tells the story of how Rheneas saved the railway, even though he was badly damaged.

During the springtime, a new line has been opened; it runs through fields of bluebells. Rusty thinks that what they need is a 'Bluebell Engine'. So, with some advice from Douglas, the little diesel ventures off on a journey to rescue one from 'The Other Railway'!

Stepney the 'Bluebell' engine feels sad that his line is so short, and longs for a good run to stretch his wheels; how delighted he is when he is invited to work on the Fat Controller's railway. Meanwhile, Percy and the others are excited themselves. But Thomas gets rather jealous...

Stepney's visit is coming to an end and Thomas, Percy and the rest are very sorry that he is leaving. But they have other things to worry about when a big-headed Diesel comes to help in the yard and scoffs that steam engines are old fashioned. However, when a bowler hat causes delay, Duck and Stepney show him just what a steam engine can really do!

Stepney is very happy with his visit to the Fat Controller's railway. But one day, whilst waiting at a signal, a cricket team's "one and only ball" accidentally falls into one of his trucks. And when he steams away, Caroline the cranky old car, driven by her Master, gives chase to try and retrieve the ball!

The engines are very excited with the news that a circus has come to town. But they become bored and grumpy when it is time for it to leave; however, Henry isn't bored for very long when he has to clear a tunnel of a mysterious, moving blockage...

Poor Oliver! Ever since his plight in the turntable well, the trucks, and their leader S.C.Ruffey, have been teasing him dreadfully. However, Toad the brakevan has a plan to stop their nonsense once and for all...

Daisy snorts about Toby the Tram Engine's cowcatchers and side plates, which prevent animals getting hurt if they stray on the line; she reckons that Toby is afraid himself and boasts that animals ALWAYS run "if you toot and look them in the eye". But she would have proved her point if it hadn't been for Champion the Bull!

Thomas, Percy and the others are invited to "the big city faraway" by a little girl as well as her friends who would like to meet them. However, Thomas becomes overexcited and has an accident. Will he be mended in time for the visit?

All the engines are thrilled when they hear that H.R.H, the Queen, is coming to visit their railway. But Thomas, Edward and Gordon are feeling sorry for themselves; things, however, get turned around for them when Henry accidentally gets covered with paint...

One evening, an extra load of fish has been ordered and there are instructions that extra vans must be added to Henry's train "The Flying Kipper". But the vans added are old; and they cause disaster for Duck, when he tries to help Henry up Gordon's Hill.

Toby is excited when he is invited to be the "Special Attraction" for a seaside village's parade. But his excitement turns to disappointment when there isn't anymore room for him. Meanwhile, Percy and the trucks are having a hard time with a disagreeable barge called Bulstrode...

Percy loves seeing the cheerful postman Tom Tipper driving about in his old van and helping him with his mail train. But Tom feels very sad when the Postmaster scraps his van and replaces it with a bicycle. Percy's wish to help his friend comes true - well - by accident, at least!

At the docks, Thomas and Percy are working hard, but the new crane, Cranky, thinks little engines are useless - "bugs" he calls them. But that night some rough weather makes a tramper crash into the shed where Gordon, Henry, James and Duck are, trapping them inside. Cranky is then toppled over by the high winds. Who will save them all now?

The engines are working really hard, and the Fat Controller thinks they need some help. He hires 3 lorries to help them, but the lorries are rude to the engines. The engines have the last laugh though when the lorries get into difficulties.

Gordon is to take important people to the opening of the new station at Kirkronan, but as he comes near his crew find that they can't stop him, and he's heading for the station wall, and fast...

It's Lady Hatt's birthday, and her husband, Sir Topham Hatt, is throwing a party for her. While driving on his way to Kirkronan where the party is being held, he accidentally runs into a large pothole in the road and this leads to all sorts of unexpected difficulties for the poor chap!

James has recieved a new coat of paint and becomes too cocky, even to recognise the dangers trees could cause. However, he learns his lesson when his trucks cause trouble for him during wet weather.

One morning, a special coach is being prepared to be coupled to Gordon to carry a V.I.P but unfortunately the turntable it is on becomes jammed. After Godon finally receives the coach after the turntable's repair, he puffs off to Kirkronan station to pick up the mystery person. But as he is now late, will he make it on time or will "gremlins" strike again?

George the Steamroller is working around the island and as usual, is causing great problems for the engines. But this time, he just takes things too far. Will he receieve his just desserts?

The stations on the Island of Sodor are entering the "Best Dressed Station" competition. Percy agrees to help Maithwaite try and win by delivering fruit and vegetables to decorate the platform. On the way there with his special load, he has an unexpected run-in with a stray ram - however, the hungry creature later becomes Really Useful when some vandals strike at Maithwaite!

Percy has been working very hard recently and feels put upon by this. The trucks find out and try to make him work even harder. Percy then takes them to the mine, but they break away and cause the mine to collapse. Will Percy escape the vicinity in time?

Toby has been sent to check the dam on the river. It has been raining heavily recently and there are worries the dam won't hold. After inspection, the dam starts to break up! Will Toby escape its wrath in time?

One evening, Henry has to take some trucks to the other end of the line, and everything is fine until he has to travel through a spooky section before a viaduct, of which Henry becomes convinced is haunted after experiencing quite some oddities...

Bill and Ben need some help at the China Clay Pits, so the Fat Controller sends a diesel, Derek, to help them out. But Derek suffers from mechanical failures, "teething troubles", and as expected, this leads to difficulties...

Stepney is bored, so the Fat Controller agrees to allow him to help out Mavis and Toby at the quarry for the day. He works well, but on the way home gets lost and ends up in the scrapyard, where diesels 'Arry and Bert take him for scrap!

The Fat Controller and his grandchildren, Bridget and Stephen, discover an old castle as well as the mine where "the little engines once worked" whilst out on a trip with Toby and Henrietta. The Fat Controller decides to turn sites into tourist attractions, but Toby hears that the mine is haunted...

Whilst waiting for his fish vans to be loaded up, a crate of fish is accidentally dropped on poor Thomas! On the way to the docks, Thomas notices that the coastal line is damaged, and on his arrival with the "Flying Kipper" trucks which are to be passed on for Henry to pull, Henry teases him about his fishy smell. Then when Henry heads off, the signalman is unaware till too late that he has accidentally switched the train onto the damaged coastal line, which won't be able to take Henry's weight for sure!

Thomas and Percy discover Old Slow Coach, who is going to be scrapped. They want to save her, but aren't quite sure how. Later, the workmen's hut is burned down and the fire engines have to borrow water from Thomas' and Percy's tanks to put it out. But where will the workmen live now?

Harold is seen by the engines suspiciously flying around and think he's scouting the area so he can find ways to replace them. Thomas tries to find out the truth, but what does the children's playground have to do with it?

Oliver has to take the Post Train for the first time, and he gets lost on the way home. But what is it that he has found?

Percy discovers from Mrs. Kyndley that her daughter is to be married "today" but has forgotten about the good luck package. Percy decides to try and help out with the problem.

The Fat Controller, his wife and grandchildren go on holiday, but various incidents keep affecting their plans!

Percy is pulling some trucks up a hill when the coupling between him and the first truck breaks. This causes the trucks to break away and roll down the line, and at a tremendous pace at that! Will Percy catch them in time before they cause even more of a disaster?

Mrs Kyndley is upset that her sister, who was coming to visit, isn't able to make it. The Fat Controller decides Mrs Kyndley needs cheering up and asks Harold and James to help out.

Toad the brake van is feeling glum as he is always seeing things sliding away from him and would like to go forward for a change. Oliver wants to help but doesn't know how. That afternoon, Oliver is pulling some trucks up Gordon's Hill, with Toad as his brake van. The trucks break away after a coupling snaps and now Toad is at the front of the train going forwards.
