Anything worth doing is worth overdoing .
I currently have 3 first gen postwar NW2 switchers pulling it now. I do however have a (single) conventional GG1 that pulls it fine, and it draws 4.5A at ~40 scale mph. By my research the Pullmor motor is good for 2.5A each and I figure that the Train Master should be about the same, so it (and the GG1) shouldn't be overloaded.
