Reply to "Here Comes the GP7 and GP9 from Third Rail"

Third Rail SD 7 or 9 a few years ago.  Click on the link.  Note that the wheel flanges are small, IMO.  This design is not a two vertical can drive.  A horizontal motor with belt drive to the fuel tank and drive shafts, to the front and rear truck.  O72 limit may be related to this drive shaft arrangement, there is a limit to the drive shaft bend, IMO.  ???If Third Rail uses the SD model design for the GP model???.
