My new layout has 3 main lines, a yard and a few sidings. I'm using a ZWL to power it all. I’d like to run both DCS for my MTH loco’s and Conventional for 2 older brand new Lionel loco’s I bought from a friend. Would using a separate terminal block for each main line and another for the yard/sidings be required? Or, can 1 terminal block be used for everything and still control both DCS and conventional ? Also, I'd like to use the 4th handle to power the switches. How would I then power the yard and sidings ? Am I better off powering the yard/sidings with the 4th handle and a separate power supply for the switches ?
Thanks, Mike
