I have several of the Lionel AMTRAK 19100 series from 1989 that were meant to be operated by the GG1. What I would to do is pull them by the AMTRAK F3 that Lionel made in the 1970s. I think the powered unit only has one motor, but is similar to the 2383 postwar units. Would this unit (run as an AA) pull 5 or more of the passenger cars? I know these have traction tires, so I think they might be able to handle the load.
Otherwise, I will have to find the red nose E8s from MTH.
