Like many of us I ran a postwar ZW for years. Then a few years ago when the smooth sine/chopped sine signal was explained I switched to the CW 80 in our Polar set as my newer loco's did smoke better when I used it. I'm currently using the CW with a Cab2.
Now I'm seeing I could use more power when pulling longer consists. I've considered the GW 180, but I always read about Powerhouse/bricks/whathaveyou...
I have no idea how/why they work so I'm looking for a little guidance.
Thanks!!
