Strange as it seems, MTH’s Z-1000 has a cut-wave output and will cause problems with those select original Protosounds locomotives. Mind you, it’s only some of the PS1 locomotives that exhibit this stubbornness. Most of mine work fine using a Lionel ZW-L, but not my 1996 Premier K4 (20-3018-1). It won’t come out of reset on cut-wave controllers, but runs flawlessly on a Z-4000.
