Here is a PS-32 Steam upgrade to a RK 0-8-0. Added the front coupler and retained the 2 pin wire harness for coupler operation. Added a reverse light. The guts fit into the tender very well and even could use some existing holes. Speaker in rear which works well.
For engine, routed all the wires and used existing spring board to run head light, had to modify contact pad to remove chassis ground. Runs and smokes very nice. G
