Stan, how you can couple two engines and run them independently...except with two DCS remotes? I can do a test run of a lashup and see how the amperage fluctuates, but I can tell you from experience when one PS3 engine runs faster than another in a lashup...and the longer you run them as such, the tension couple slack can be quite high and will eventually break the couplers. I can get around this by putting the faster engine in the rear and it will push the slower one and pull the consist.
fyi, when operating independently there was no big increases in amps except when smoke units kick on...the bipolar has a intermittent steam generator that kicks on every so often, pretty neat effect. Lionel bipolars have the same feature but difficult to see the smoke.
