Train Idea: the heavy hauler.

Design: it's based on the central pacific Mastodon locomotive with it's tender pulling 5-10 boxcars with a caboose at the end.

Speed: 85.

Pros: fast, can carry a lot of stuff, boxcars can't be shot through, and sparks from the chimney can be used to start fires.

Cons: the thing is pretty fuel hungry and is pretty loud and will attract lots of zombies if you aren't careful.

Cost: 200 bonds.
