Conrail. Ex. Penn Central unit #80041....is this a crew cab with sleeper! May 5, 1986. According to Zach J. Bloomquist, it was part of a Dewitt geep program on the New York Central. It might have had something to do with a project to make something for the RS3m rebuild program that was a one of unit. I want to acknowledge Zach for his assistance with identifying many of the diesel models in my photos.
