Can do with 2 different LionChief Plus engines in remote mode using 2 remotes or the universal remote.
Conventionally, can do using block wiring and fiber pins and having properly phased transformers. However, it makes me a little anxious to run 2 trains on the same main line track , so I opted for 2 interconnected and independently powered main lines.
Fiber pins are in the usual places in these 022 switches plus there are fiber pins where the switches meet between the outer loop (main line on top) and the inner loop (main line on bottom). I use an MTH Z4000 transformer in which the left throttle controls the inner loop and the right throttle controls the outer loop.
Trains have plenty of power and run smoothly between the inner and outer loop. Set the throttles so the train goes at approximately the same speed between the inner and outer loops.
I also use fiber pins, Atlas switch controls and a ZW transformer to independently power 8 sidings on my layout. This enables me to park a locomotives on each siding while running other engines on my 2 main lines. ZW must be properly phased with the MTH Z4000.
This arrangement enables me to run 2 independently powered trains (one train on each loop) or one train from one loop to the other loop, while other locomotives are parked on the sidings. Arnold
