I solved that issue by using the TIU in passive mode. I don’t need any track power passing through it. I power the TIU with the Aux power input. I strictly use the Powermaster to power the rails. With the TIU in passive mode, you can turn on full voltage on the Powermaster with the Aux 1-9 command, and off with the Aux1-0 command. Or, you can vary the voltage coming out of the Powermaster using either the MTH app or the Lionel Cab2. Either method of control works. I can even switch in the middle of running trains. Or use the app for train operation, and a cab1 for a stationsounds car. Keep in mind that when you power up the track with the Powermaster, you get DCS operation (TIU in passive mode sends watchdog signal when power is first turned on. )
