I use the Z1000 on my layout. It gives enough power for 3 MTH Steam Engines(Big Boy, N&W 611, and NKP 765), all with smoke on. 5 Passenger Cars and a lighted caboose. So I would think it should be able to run 2 Dual Motor Diesels and 10 Passenger Cars. I have also run it with a Steam engine and a diesel MU'd(lash-up) together with the Amtrak 4 Car Superliner set and 5 N&W Passengers cars. Unless the 10 Passenger cars use incandescent lighting then it may not be able to support the Amp Draw of it.
