Living Train

Living trains are a species of trains with white, slightly realistic faces that can talk. They are from a British preschool show, Thomas & Friends.

They are descended from non-living trains that were genetically engineered in 1860s by Maverick Hunters to be soldiers and protect them, but ever since they retired, they now live in peace (for the most part) with all sapient species (except vampires, dragons, bonggambies and their allies due to bloody conflicts with them). They are omnivores that feed on the same food as many other sapient species and beings, and they don't need coal or fuel to power them up.
