I own a Lionel Postwar Super O set (conventional) with KW transformer currently controlling only one loop. I am interested in getting into command and control. I understand all the capabilities of going to a LEGACY system in that it allows for future growth and powerful features. But for now, I thought I'd just start with a PowerMaster and a CAB-1. I need clarification, however as to whether I just need those two components or do I also need a 6-12911 command base? I've read that the CAB 1 talks directly to the PowerMaster, so maybe I would only need the command base if I were running TMCC.
Later, if I want to move up to LEGACY, including acquiring LEGACY class locomotives, or retrofitting my old PW locomotives with Electric Railroad decoders, I gather that the path would be a PowerMaster Bridge, and a #990 Legacy Command Set. But I would keep my PowerMaster? Or do I have to replace my 6-128687 with a Legacy 6-37146 PowerMaster? As you can see I am fuzzy on this upgrade path if I start out cheaply with just the CAB 1 / PowerMaster.
