Model Train Power Packs How They Compare

November 20, 2005

There is a big choice when it comes to power packs for model train layouts. Power packs come in a variety of designs to suit individual requirements. All power packs contain a few basic components, including a transformer to provide the 12 volts, a throttle to vary tile output voltage, and a direction switch to control the polarity of the circuit. Power packs also have screw terminals for the track (which is DC) and AC accessory connections.

Larger units may include a larger power supply as well as additional electronic features such as: operating modes, pilot lights and meters, and multiple terminals for accessories such as add-on walkaround throttle units. These units make it easier to operate your train, enabling you to follow it as it moves around the track, rather than standing in one spot and watching it.
