I bought all three road numbers of MTH's PS-1 equipped Chessie GP38-2s just so I could MU them. One was good and the other bought broken to fix up. I got one of the two working, and the other still needs new motors. At some point they will get ERR upgrades, but it's still fun to run the two conventionally.
On a side note about the two that I got as fixer uppers, it looked like someone tried to make them an MU set. The one that works now looks like someone wanted it to start backwards. With PS-1 this is easy, you just swap the two motor connectors on the board. But the person that tried to do it didn't know that and instead removed the wires from the motors and reattached them. When doing so shorted to the motor case and thus it didn't work anymore. I cleaned it up and it runs fine. The other one has a motor that draws a pant load of current, so I need a new motor and it'll be ready for service.
