OK, I feel better now.
Let me explain.
I have post war, MPC and more modern conventional, RMT, I think a Kline conventional, LC, LC+, LC 2.0 and 2.0+, Legacy, and PS1/2/3. Currently I have 2 CWs, the little thing that came with the bump and go trolley, a Cab 2 and DCS with I think a Z1000. Also a PW ZW, a 1033 and one of the old small set transformers. I haven't used the ZW since I smoked one of my Christmas engines in a derail accident and scarred the carpet when the wires smoked. I have decided to go with Lionel 91s. I have 2 on order and I'm going to order 3 more.
I like running conventional (I'm old school) but I do have modern Lionel and MTH. The PS2/3 do not like the CWs and one of my RMTs Beeps was funky on testing and my RMT based on old Kline switcher acts badly and I suspect that part of the issue is the CW. They had all worked fine previously and I think I was using the CW back then. But, right now the CWs are the only common element for all these issues.
I have the Cab2 and the DCS for when I want to run the Legacy and PS2/3 for the full benefits of the features. I think I would prefer full sine for the postwar, MPC and other conventional
I've looked for an MRC as a backup mostly because of the modern electronics protection. Oops, just got an offer on the MRC AC Throttlepack I was looking at on the auction site. I took it.
So, if I go with the ZW-275 and the 1033 (or another PW throttle) with Lionel 91s could I use that to power the conventional engines and run one line to the Cab2? I can just use the DCS as is with the supplied power brick. And using the DCS to control the Legacy if I get that far. Which means the Z1000 will be powering that. It will not be a huge layout. 2 loops, maybe 3 and some switching. I already have the TVS diodes for the PWs.
Does this seem reasonable? Postwar transformers with TVS and Lionel 91 circuit breakers. For most applications.
But ditching the CW80s is a priority. And I have a shop nearby that will take them.
