The idea for this thread was suggested by Georgeward in a related thread pertaining to "The Delaware Lackawan". I'll start, but I won't steal his entry.

In my hometown there was a railroad, the Delaware, Lackawanna & Western (DL&W). However, to the local folks it became known as the Delay, Linger & Wait, for not too flattering reasons.

Anyone else have a favorite railroad with unusual nicknames using the official letter abbreviation of the road?
