I picked up two partially complete engines (Really doing the PRR but # above is different.) First, both are missing the sound boards. Will the train run in conventional 3 rail without the board? (I have heard that it will not.) I do have the tender with the frame for the 9V battery and I assume the board is on the other side.) My parts appear new on the GN engine. There was snipped wiring on the frame of the PRR engine. When I got it out. and compared it to the new loom/motor, I have a long black wire now as well as the long pink wire. And still have the short pink wire for the rear ground. To get the unit together, I need to know where to properly attach these three wires. (I did write down where I took the wiring from the original locations.) The lamp/smoke unit is attached to the loom as well.
I do need a set of trucks for the tender and a draw bar. I do have someone at MTH helping out as well for the parts. Any help will be appreciated. If it will help, the drive rods on the PRR are chromed and the ones on the GN unit are black.
