Help - 2T Shay motor draw

[Gonzodagreek]

I want to size my sound decoder correctly and need to know what max amp draw is from this engine.  I do not have the specs for it as I bought it second hand.  Please help by indicating the amp draw of this G Scale, 2 Truck Shay unit.

Thank you.

I'd plan on 2.5 - 3 amps stall current. Most likely in "normal" operation it will draw somewhere around 1 amp give or take. My 2-motor Climax and 45-tonner both pull just under an amp on average. You'll draw more on starting the train and also if you've got steep grades (which many folks who run Shays tend to have).

Later,
