The PWR-56 is a Power Supply that can be used to supply power for your locomotives, turnouts and other accessories. The PWR-56 has 56 Watts of output power! That is enough power to drive 15 or more typical modern HO scale locomotives! Further, each PWR-56 is equipped with Direct Radio, so a RailPro controller can be used to control, setup, and monitor the PWR-56. Also, the PWR-56 can be used as a Direct Radio Repeater.
