Why It Was Cancelled

 * 1) While the first film made money, it did not make enough to be deemed 'successful'.
 * 2) Many script re-writes were made during production of the first film, 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 its production and if so, would likely already been set in the story for its plot meaning that the audience would not know who he is and may have also been frightened by him. It's also 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. Since then, they have all been straight to VHS (until the mid 2000s) or DVD, although there was one planned for a theatrical release in the early 2010s.
 * 2) A straight-to-DVD movie known as Calling All Engines! was released in 2005 taking place after Thomas and the Magic Railroad with the main cast returning from it (not counting human characters).
