I'm in the process of planning for my future layout. I currently have the CW-80 as my power source, but with more than one train or long passenger trains, they are proving to be underpowered. I started using them before I learned that they didn't work with PS-2 locomotives. But now that I need more power and some newer MTH locomotives are really tempting (I'm looking at you Erie Triplex.) I'm trying to decide which transformers I should start saving for. I really like the look and feel of the CW-80, and all the kids I've had run my trains, from 1 year old on up, handle them very well, so the GW-180 seems like the logical next step. But I don't want to get it if it'll continue to limit my locomotive selection.
So to cut to the short of it, does PS-2 or PS-3 locomotives have any issues with the Lionel GW-180 transformers? I run conventional and would like to run at least 2 trains trains at a time, both possibly passenger trains.
