Custom Scenery Exchange / The Big RCT2 Coaster Train Guide

I thought this might be a pretty neat idea. Obviously, a lot of trains are very obvious to identify, such as the custom trains that are made with a specific company in mind or the official trains that were clearly inspired by a company. But I do think there are some IRL trains that don't have an explicit or implicit match, so how about we collect them here so everyone has a good reference document? Also, possibly link where they come from for people who might not have them yet.

B&M:

Sit-Down Looping Coaster - Twister Roller Coaster - Official RCT2

a lot of trains will soon be available for download on a website similar to AE or X71 pages in RCT2 style
