User:Trainsandotherthings/50 state challenge

This is a little challenge I have given myself. The task is simple: bring one article for a railroad, past or present, from each U.S. state and the District of Columbia to good article (or featured article!) status. The railroad in question must have or had a significant presence in the state in question (for a shortline, this can still be only a few miles of track), and no article can be used more than once.

The table below keeps track of my progress.
