Reading GP7 switches a loaded hopper.
Though I will run RDG equipment onthe layout along with my homeroad stuff, the geeps that I painted for RDG are not included. They are mainly for running at NTRAK shows. In the area, and era I'm modeling (north of Wiliamsport, PA in Sept 1956, the RDG ran primarily cab units(FTs, F3s&7s and FA1s/FB1s). I think they still look right at home though.
