Thanks for the info H1000
I do have an Amtrak Genesis Cab 805 with PS1 in phase 3 paint.
I hadn't thought of running it with my PS3 in phase 4 paint, but I see a lot of mixed schemes when I watch videos of real trains running. So now I think I might want to do this after all.
Could a PS1 run in a lash up with PS-3?
