GP7 by @RailfanEthan

Scores: 7/10/9
Well, it accelerates too fast and shoudn't be like that irl... but other than that this loco has reached perfection. I like the interior especially.

Hey guys, trains don't accelerate as fast as cars do!

Anyways. Thank y'all for participating! It proved worthiness of train builds on SP!
