While we are dedicated to battery power here at G-Scale Graphics, we know there are still some of you that want to enjoy all of the features RailBoss 4 has to offer, and still keep your track power. So we have added a nice little Track Power Adaptor. It is similar in size and function to our Battery Conversion Modules. It provides a power on/off switch that extends through the floor or a bulkhead, has a bridge rectifier to allow you to run off of constant track voltage of any polarity, additional filtering to tame that intermittent track power, and screw terminals for track power in, and two sets of power outputs; one for the RailBoss 4, and one for your sound board.
