I have the DCS Remote Control Set with TIU installed on my layout, including the variable voltage channels functioning as fixed voltage channels. I also have 2 Z4000 transformers, one of which powers the 2 interconnected but electrically isolated main loops, and the other powers the 8 isolated sidings with heavy duty Atlas connectors.
I also have a Z500 brick hooked up as the auxiliary power source powering the TIU, and I have the Z4000 Receiver, which is not yet hooked up. I have Barry Broskowitzs book (3rd edition).
I am soon going to hook up the Receiver to have Z4K Tracks, and will strictly follow Barry's instructions for doing that.
When I hook up the Receiver and try to run a conventional Postwar engine on the Z4K Tracks for the 1st time using the DCS remote handheld, my fear is that if I do something wrong, the Postwar engine may fly off the layout and crash to the ground with the Z4000 set at 18 volts.
Is my fear unwarranted? What can be done to prevent my Postwar engine from becoming a runaway train?
