Reply to "Two trains onsame track?"

I have run 2 trains on the same track about 30 years ago. If you are adept at soldering, you place a heavy duty diode inline with the loco center rail pickup inside the engine. And on the other engine, solder a heavy duty diode but with diode in the opposite polarity. Then on my ZW transformer, I placed the same diode on the voltage output of the left throttle (A) and placed a 2nd diode on the right throttle (D).

You then have 2 separate throttle controls, with left controlling one engine and right throttle controlling the other engine. No wiring blocks to worry about. The engines will not get full power because they are running with the diodes, but you do get totally separate control for 2 engines running at their own speed. Also need to turn off e- unit as I recall.

Can you run other trains without any problems and does the transformer diode affect the speed of other engines?
