When you are ready for your layout to grow you may need additional power. We carry power supplies from several manufacturers. Some power supplies are designed for train control while others are better suited for lighting and accessories. You can also add additional realism by adding smoke and sound. Recreate factory smokestacks, house chimneys, fires and more. You can add sound to simulate busy cities, factories, farms, and trains depots. The only limit is your imagination. We carry power, smoke and sound supplies appropriate for HO, N and O scale layouts.
