Standard Gauge Engines
Thomas the Tank Engine, but he's (for the most part) built off the cab model featured on the original SI3D model.
This is a slightly modified version of SI3D's James. He notably has differing brakepipe positions depending on the era they're supposed to be from, and is pretty easy to reskin.
Percy but he kinda resembles the spare model made by the Reverend. Original model made by Lachlan.
It's Wilbert the Forest Engine with a Giesl Injector instead of the standard funnel. Based on the real life engine, Repulse.
Standard Gauge Rolling Stock
Edward's Tender, but it's sides are painted red to resemble the model from Carson's Video Workshop.
