Tom Jerry is a small freight engine based at Kahlville Junction. Tom Jerry (better known as T.J.) is a heavy goods locomotive, typically working the Crotoonian National mainline. Originally owned by the Onion Pacific Railroad., T.J. is often entrusted with handling heavy goods around the railway, like iron beams, bricks, lumber, slate, and many other things! He's a hard working loco, and though he's not as big as other engines like Gordon or Montana, he's a very strong little tender engine
