Thomas & Friends - Seasons 18, 19, 20, 21

The bigger engines tease Edward for being old and unreliable, especially Gordon. But when Gordon sees some red trousers blowing by the tracks, he mistakes them for a red danger flag and stops, ending up stuck on Gordon's Hill. Edward has to come and give him a push, but Gordon doesn't even say thank you, so Thomas and Edward decide to teach him a lesson.

Annie and Clarabel are always complaining to Thomas about going too fast. Thomas likes to tease them, by going too fast or too slow (so Annie and Clarabel will ask him to go faster again). But when Annie and Clarabel find themselves coupled to Caitlin by mistake, they get a taste of what going fast is really like, and poor Thomas gets frightened that they might be taken to the mainland forever.

A delivery of pipes is being unloaded at Brendam Docks. But the engines start to hear scary spooky noises and soon Salty has them all convinced that it's the sound of the Flatbeds of Fear. Only Emily insists that there must be a sensible explanation, however it turns out Emily was right about there being a sensible explanation. The sound was just air blowing over the pipes!

Paxton likes to be friends with everyone, diesels and steamies alike, but it's not easy to be friends with Diesel. Diesel gives Paxton a terrible fright when he makes him think that all the other diesels have disappeared. When Diesel runs out of fuel, it is Paxton who takes him by surprise by offering him help. Paxton gives him a push to the fuel tank and a taste of what friendship might be like

Toby is always nervous when he has to go through Knapford Junction with the big gantry signal over the track. One day Toby waits nervously for his signal to change, but it stays on red. He waits and waits, holding up other engines, but the signal doesn't change. Sir Topham Hatt is very cross until everybody finally realises the signal is broken.

Oliver is always telling his brake van Toad about his adventures and Toad longs to have an adventure of his own. So when the chance comes to work with James, Toad is very excited. But James doesn't like pulling cars and goes too fast and then, when a coupling snaps, Toad gets a bigger adventure than he bargained for.

When Duck gets stuck on some flooded track, James is sent to fetch Rocky to rescue him. But James doesn't wait for Rocky to secure his crane arm. Without a signal to warn them, the other engines don't stop, and what began as one small accident for Duck soon escalates into a much bigger one involving several other engines!

It's high summer when many more people visit the island. When Duck tells the other engines about the slip coaches they used on the Great Western Railway, which could be uncoupled at stations without stopping, James tells Sir Topham Hatt and claims it's his idea. But James has never used slip coaches before and soon runs into trouble.

When Thomas and Diesel are sent to collect cars from the Ffarquhar Quarry, they argue about who should be the back engine. But then Diesel suggests he take the cars with Mavis and leave Thomas to look after the quarry until they get back. When they don't come back, Thomas gets fed up and decides to take another load of troublesome trucks on his own and then there is trouble!

Thomas is on his branch line when a passenger pulls the emergency cable and he has to stop quickly. To make matters worse, Clarabel has a wheel flat after being dragged along with her brakes on. So the next time Thomas sees the bird watcher he refuses to stop to collect him, but he soon learns that that's not the right thing to do either.

Everyone is happy at Christmas time except for Duncan the Scottish narrow gauge engine, who seems to be grumbling even more than usual. But Victor offers Duncan a new coat of paint if he can only not grumble for one whole day. Duncan rises to the challenge, but it is not so easy for an engine who likes to grumble to give up the habit of a lifetime.

Duncan is the grumpiest engine on the narrow gauge railway. He is always complaining about one thing or another. But when Duncan gets a very grumpy passenger, Duncan finds his grumpiness very annoying. So he decides to do everything he can to make the grumpy passenger stop complaining. But Duncan soon learns that you can't make everyone happy.

It is Christmas Eve and a lot of passengers are coming home to Sodor for the holiday. Connor can't carry all the passengers who are trying to get on his train. It becomes a race against time and all the engines have to work together to clear the tracks and get the passengers home in time for Christmas.

The whole island is celebrating Christmas and there are decorations everywhere, but it doesn't look very Christmassy at the scrap yard. Percy starts to worry that Reg is missing out and he tries to find something to take to Reg to cheer him up.

One day while repairing an embankment, Marion strikes something hard and insists it must be the mast of a Viking Ship. It looks like a water pipe to Thomas but Marion is adamant that it isn't. But the next day Thomas notices flooding near the bank and then there is a landslip and Marion has to admit her mistake and help prevent an accident.

Percy misses his friend Gator and keeps thinking back to the times they had together. It's making him sad, so the other engines advise him to keep himself busy to take his mind off it. Percy is frightened to go in after them, until he remembers Gator again and what Gator taught him about being brave!

There is a coal shortage at the Clay Pits. Timothy warns Bill and Ben to go easy and spare their coal. But Bill and Ben don't listen, teasing each other, and Timothy and messing about, until they do run out of coal! Luckily Timothy runs on oil, so he manages to keep going, delivering clay to the docks and bringing back coal for the tank engine twins.

When Spencer brings a Very Important Passenger from the mainland, he is so determined to be on time that he doesn't notice he's been sent down the wrong track. The other engines all compete to be chosen to take the V.I.P. back to the mainland, but rushing to do things quickly and showing off, only leads to confusion and delay.

Christmas time on the Island of Sodor and Gator is coming back after working in a land far away for a long time. He is looking forward to seeing his old friend Percy. When Percy hears that Gator is back, he is very excited and immediately heads off to see him. But the two engines keep missing each other and soon they both begin to have doubts about whether the other one wants to see them after all

Gator is waiting to be loaded onto a ship, but the ship is delayed. He sets off to collect Oliver's cars and promises to bring them back before morning. But Gator's lamp keeps going out and he decides not to stop or he will be late. Toad, the brake van, doesn't think it is safe and they argue, but in the end it is Toad's bright idea that helps Gator deliver the cars in time.
