I believe the changeover to a vertical design for GP7's was done with the C&O bell ringer, although the truck used appeared to be similar to the new PA type truck, also vertical drive. The horizontal can motor truck was based on the original Gilbert truck design. The new sideframes require a shorter truck.

I'm not sure what you are trying to say Rich, sorry, my view on it is that Dave shows above a design drawing of the basic Baldwin truck which is going to be used in the new GP with a round can motor which is not shown. All I am trying to say is that instead of using a normal round can motor in the Baldwin truck, is that a flat can motor is subsituted which could then be used both ends. The flat can motor is sitting vertical and would have enough room in the long hood to fit easily and still have enough room to rotate on R20 curves. You would then get a locomotive with eight wheel drive, yes, it would mean some additional re-design but I wouldn't think it was insurmountable to do.
