Thomas' Christmas Party is the twenty-sixth and final episode of the first series.
It is Christmas time on the Island of Sodor and Thomas and Toby are very busy carrying people and parcels along the branch line. Despite Annie and Clarabel complaining that they are overloaded, Thomas retains his festive spirit.
Near his branch line is a little cottage. This is the home of an older woman named Mrs. Kyndley. Thomas always whistles "Happy Christmas!" to her and agrees that Christmas would not be the same without her.
At the sheds, all the engines have been polished but Thomas does not mind and tells them he wants to throw Mrs. Kyndley a party to thank her for saving him from a landslide the year before. When she was ill in bed, she waved her red dressing gown out the window to warn Thomas and the Fat Controller sent her to Bournemouth to get better as a reward.
All the engines agree that a party is a great idea and hope that the Fat Controller agrees as well. He does, but on the day of the party, there is a heavy snowfall, trapping Mrs. Kyndley in her house. Thomas bravely puts on his snowplough and sets off with Toby to rescue her and soon, they arrive at the cottage which is covered in snow. Thomas whistles to Mrs. Kyndley to tell her they have arrived when suddenly, Terence arrives with his snowplough to help clear a path from the cottage to the railway. Once everything is cleared away, Percy takes the workmen home and Terence stays behind to look after Mrs. Kyndley's cottage.
Thomas and Toby take her to the shed, where the party is supposed to be, but as they arrive home, they find the sheds in darkness. Suddenly, a switch is thrown and the sheds are covered in lights. The Fat Controller congratulates the two engines, everybody sings carols and Mrs. Kyndley says it is the best Christmas party ever.

- This is the first episode written entirely by Britt Allcroft and David Mitton, and not based on a Railway Series story.
- This episode was adapted by the Rev. W Awdry into a book of the same name nearly two months before airing.
- A flashback of The Railway Series story, Mrs. Kyndley's Christmas, is featured in the episode, never having been depicted in the series prior.
- Stock footage from Thomas' Train and Thomas, Terence and the Snow is used.
- The backing vocals of We Wish You a Merry Christmas are likely from Mike O'Donnell and Junior Campbell.
- This is the first Christmas-themed episode.
- The platform the Fat Controller is standing on is made out of LEGO bricks.
- The text in the end credits is red in the original version to suit the Christmas theme.
- Only one line of the Christmas carol is sung in the Welsh version, replacing other lines with Thomas's theme.
- Christmas lights are used for the decoration lights in Tidmouth Sheds.
- This is the last episode where Thomas has a realistic-looking brake pipe.
- This is the last time Thomas' whistle supports are blue until Thomas and the Magic Railroad.
- This episode's airdate in Australia holds a few significant traits:
- It aired only a few days after Babar and Father Christmas, which was shown on Christmas Day.
- It was just a few days before it was screened individually on ITV in the UK, on Wednesday the 30th.
- Its airdate happened to be the birth date of American actor Thomas Dekker, who voiced Fievel in An American Tail III-IV and Littlefoot in The Land Before Time V-IX.
- In the opening shot, Clarabel is facing the wrong way.
- When Thomas has his snowplough fitted, one of the workmen has Blu Tack on his leg.
- In-between the stock footage from Thomas, Terence and the Snow and Thomas and Toby stopping at the cutting near the Cottage, Toby loses his brake van.
- In Ringo Starr's narrations, Thomas, Edward and Henry's whistles are heard with the last part of James' whistle heard intact before the others. In the George Carlin dub, when the engines whistle, only Thomas, Edward and Henry's whistles can be heard.
- At the Christmas party, Henry is in his old shape.
- In the Sprout Channel broadcast, around the time the engines save Mrs. Kyndley and the time Thomas gets back to the sheds, the narration is dramatically out of sync.
- In a deleted scene, Thomas' eyes are wonky.
- When the Fat Controller stands on the platform, some Blu Tack can be seen under his feet.
- At the beginning when Thomas whistles "Happy Christmas" to Mrs. Kyndley, Clarabel is the front coach and facing forwards.
- In the George Carlin dub and all other non-British narrations (excluding the Spanish and Brazilian Portuguese dubs), Ringo Starr can still be heard when the engines are singing.
- In George Carlin's narration, it is said said that Terence was "working hard to clear a patch to the railroad line," rather than "clearing a path."
- In the close-up of Gordon when the narrator says that the Fat Controller has bad news, Tidmouth Sheds is missing.
- In the close up of Thomas at the sheds, the camera shakes a bit.
- At the sheds:
- The engines eyes are wonky.
- The chimney above Gordon's shed is crooked.

- Edward is tilted a bit.
- James's eyes jolt down at one point, and his left buffer (viewers right) is scratched.
