If you have seen my other threads, you know I talk mostly about steam, so this will be a change of scenery for me.
I will give a description, and you post your guess, and your favorite diesel locomotive. I will announce the locomotive when someone guesses correctly. If not, I will post clues. If no one is correct I will announce the locomotive at 12:00 E.S.T.
These locomotives came onto the railroad scene in the 70's and served until the 90's. They were the first of their kind. There is only one survivor today. These locomotives were a part of everyday life for many people. Two briefly served in excursion service.
