Actually, lowering the voltage would lower the current draw too with a constant load. Of course a motor is anything but a linear load, and it does tend to draw more current at slower rpm. In any case, you're not going to break it, since the 9v train (...) (25 years ago, 23-Aug-99, to lugnet.trains)

Okay, how's this for an idea: Most electronic stores stock a kind of universal power converter. These have several output settings, including 9v and 7.5 volt. If you use the 7.5 volt setting, the train never gets enough power to derail on curves. (...) (25 years ago, 23-Aug-99, to lugnet.trains)
