John Z,
This is one of the great things about DCS and the TR modes, of which there are actually 2, if you own the Z4K. Sometime if you invest in one, there is another TR
mode that is operated with a side receiver on the Z4k transformer, opening up even more conventional engine running options, along with the TR mode Barry has just advised you how to use. DCS can actually control both Conventional and remote control engines at the same time, even on the same track, if you understand how to
set things up. DCS is a learning experience in itself, with both conventional and remote control operations from the same hand held remote. Way cool stuff, once the owner understand how to operate it all the options, at the same time.
