@gunrunnerjohn: Maybe my method wasn't the best. I had my fluke connected between my transformer common post and the return that feeds my dad's layout. We let the big engine run straight up the incline (it won't make it around the 063 curves) and kept adding more cars until it didn't want to climb anymore with applying 12 or 13 volts. (it was a really long train, and we did this exercise for several different trains and got similar results for almost all of them except for an old PW AC motor that I modified to work with a PS1 board that took almost 5 amps) .

The motor in the S1 was a Pittman 9234 series like your chart shows:

Maybe my configuration wasn't good, but I'm 90 percent sure I never saw above 2A. But now you've got me worried. I put some breakers in on each of my power districts (5A) and none of them ever popped even after several seconds of the loco sitting there, so I really don't think it could have been pulling 14A.

Is there that much of a difference between the AC amps going to the board and the resulting DC amps actually feeding the motor?

If the big motors can stall at 14A, then I assume that none of the Tsunami decoders could work with it? The 4400 lists 4 amps, I assume that means continuous but the Soundtrack user manual definitely says stall current:

..Did I order the decoder too early LOL...
