[quote]QUOTE: <i>Originally posted by twcenterprises</i> <br /><br />Using your trusty amp meter, add weight until the motor draws just under an amp (about .8 amps or so) with the wheels spinning. Any current draw above that will drastically shorten the motor's life. Of course, you may not have enough room to add that much weight, in which case, add enough to make it "scale weight". A real SW1500 weighs about 250,000-260,000 pounds, which calculates to about 6.3 ounces, give or take. <br /> <br />Brad <br />[/quote] <br /> <br />That's more of what I am worried about, and that is, the motors life. I have a P2K SD60 that must have some serious weight in it. The thing is probably the best running locomotive I own, but how long could it last lugging that much weight around? I read in a thread a while back about how a person was having trouble with this same locomotive(SD60) while running it for long periods of time (overloading the power pack). The SW1500 needed extra weight. I just don't want to sacrifice motor life for the ability to pull X amount of cars.
