@bmoran4 posted:@ArtsModelTrains, you can think of the ZW-L as being four Legacy PowerMasters in one housing.
I have the ZW-L but there is no mention of the built in PowerMasters being Legacy PowerMasters. If In fact if they were they would be better able to control MTH PS engines. The TPC’s control MTH PS engines better.
in addition the instruction on controlling MTH engines are rather incomplete and vague.
