Is it an episode of The Raccoons, perhaps this one?: http://raccoons.wikia.com/wiki/The_Evergreen_Express!
Edited by RedScharlachI guess that is the one, despite me being sure it wasn't The Raccoons... Still, I know I saw a removed rail with my own eyes, it's strange the episode summary doesn't mention it. Maybe it was an animation mistake I picked out? Thanks for that.

One of my very first memories was from watching a TV show in the early 90's. It was your typical 80's cartoon animals show (I'm pretty sure it was a rerun). Something about a race with a locomotive (finish line ribbon), the historic rail line and/or town being demolished by the villain if the protagonists didn't win, and the right-hand rail being missing just before said finish line. Not sure how it ended, the TV was probably shut off before I could see.
I don't think the episode was from Duck Tales or that "80's pro-environment cartoon" with cartoon animals whose name I can't recall save for beginning with "The", though I could be wrong.
