Not all big power is created equal, as you add switches, lights and locos to your layout, and enjoy big scale railroading, you’ll need big, controlled, safe power. Not all big power is the same. While others may claim huge output, it may only be for an instant. Continue to draw their top power and their unit may overload and shut down. Not with MRC. MRC’s power claims are for lasting power. You want power that can take you from slow crawls to highballing with controlled realism… without short changing your power-draining accessories. You want power to climb steep grades with ease.
