I'm fairly new to O Gauge. I would like to get Lionel's Legacy Control Cab-2 System. I wanted to get feedback on power options for the Legacy system. I plan on running conventional (including my dads postwar 4-6-2 steam) and Legacy locomotives. When I look at their latest track and power catalog, they say if you want to run conventional and legacy, you can get the ZW-L (which I'm not planning on getting because of the cost) or the powerhouse power supply and the Legacy PowerMaster. I talked to my local train store and they said that you can just get a conventional transformer like the CW-80. I want to be able to run 2 or 3 legacy locomotives at once or do a lashup. What do you recommend?
