Thomas and the Magic Railroad 2

Thomas and the Magic Railroad 2 was a cancelled sequel to the movie 'Thomas and the Magic railroad', it was being worked on during production of said film.

Why it was cancelled

 * 1) The original, while still made money, did not make enough to be called 'successful', so a sequel would probably do worse.
 * 2) Many script re-writes where made during production of the first, meaning that the team producing the sequel may have had a hard time keeping up with the new scripts and story alterations.
 * 3) P.T Boomer was likely to still be in the script during it's production and if so, would likely already been set in stone for the plot meaning that the audience would not know who he is and may have also been frightened by him, the reason why he was cut from the film.

Result

 * 1) This sequel has been cancelled, and due to the failure of Thomas and the Magic Railroad no other theatrical Thomas films have been released, although there was a planned one set for a release in early 2010's.
 * 2) A straight-to-DVD movie known as 'Calling all Engines!' was released taking place after 'Thomas and the Magic Railroad' with the return main cast from it (not counting human characters).
