Jul-21-01, 09:21 AM (EST) 1. "RE: What are these things in the front" The red and blue holes with the covers over them are known as "M.U." connections. M.U. stands for "Multiple Unit", a.k.a. more than one locomotive. These connections ( on a freight diesel ) make it possible for one engineer to control as many as 6 locomotives at a time by transmitting all his control movements to the trailing units. Conrail units sometimes had a wording on the cab side called "Select-A-Power". This allowed the engineer to shut down ( or re-start ) up to 5 trailing units for economy reasons ( all units to get moving or go uphill, less power on flat ground ). I think on passenger units some of these connections also transmit heating and electrical information to the head end unit for train environment. In your pictures these are usually covered up with the doors you see on the outside corners. Apparantly the yardmen were in the process of hooking up another engine when you took those shots. Jake.
