Thomas and the Special Letter

"Dear Thomas and all the engines, please, can I meet you? My friends say they would like to meet you, too. You can come to my house for tea, but my mummy says there aren't any railway tracks to my house. Can you come to the station instead? Thank you very much!"

- The letter

Thomas and the Special Letter is the twenty-second episode of the fourth season.

Plot
Thomas is surprised to see the engines traveling to Tidmouth Sheds, and follows to get to the bottom of the matter. It turns out the first eight engines have been invited to London by a little girl eager to meet the engines, and the others are to do their work. Thomas is paired with Oliver to show him his branchline. Thomas is feeling excited and boasts about his race with Bertie, unluckily crashing through the buffers and into a wall. The workmen race to repair Thomas in time for the trip, and manage to do so just in time.
