I've been considering an MTH steam locomotive with PS 3.0. As I'm not interested in rewiring my layout for the MTH System, what features of an MTH PS 3.0 locomotive will my ZW-L Transformer, or TMCC, or Legacy operate? Direction, Bell, Whistle, would be sufficient for this purpose, as I'm more interested in the particular MTH engine's attractive detailed appearance.
As always, many thanks!
