Time...It marches on...without ever turning around to see if anyone is even keeping in step.
I have a three cylinder SP 4-10-2 that I would like to add DCC and sound to.Is this something that could be done with a cuctom made disk placed on a driver? This is compleatly new territory for me, as is the loco, and I want to do it right.
