@CurlSnout posted:If I use the KW to run only ONE train (I have the GW-180 for the other loop), are all of the 190 watts available? Or, do you only get 95 watts per track (0.5 x 190 watts), regardless of whether you run one or two trains?
All 140 watts output(190 is the input rating) of the KW is available in any combination, up to 19-20 volts. You will notice an improvement over the 16 volt 65 watt output of the 1033.
