The activity on BPT is too high sometimes.. I was going to say who it was right when I saw the image and Sun beat me to it (I know 'every' character ever introduced in the TV series).
Blame Sharon Miller who designed her (Belle) with water cannons that use the same water used for her steam. Even Andrew Brenner or Sam Wilkinson didn't improve that. I never even thought about the crowd control idea (though Flynn would do it better than Belle, if anything). I've just remembered that in a short lived fan series called Ghost James, the deceased James replaced Belle's water with petrol and made her set Diesel on fire. Also, those events are called Day Out with Thomas.
The TrackMaster version has better proportions than the Plarail, but the only problem is the false coupling rods (some owners have cut them off and replaced them with normal ones. Dieselworks123 used Henry/Gordon/Hiro rods for his).
