First the Z4K tracks vary the transformer output. They start out at zero and you scroll up and down the voltage of the transformer. They can be set to go from zero to 18 volts with 1 click of the thumbwheel, but to run conventional, don't set them that way. To start out just use a caboose or other car with lights instead of an engine to to see if you can operate the transformer with the remote. Works like a charm.
I did have a problem with one engine years ago going over a Ross switch that would make a small spark causing the transformer to drop to zero. I just took a dremel and cut a very small piece out of the offending rail and all was good. The nice thing about the Z4K tracks is that you don't have to reset any thing. You just scroll the voltage back up to get your train going again.
