The MTH HO scale Allegheny 2-6-6-6 models one of the most powerful steam locomotives ever built. Watch this HO scale steam locomotive haul model trains on the Model Railroader staff's layout. The model features the MTH Digital Command System that operates on direct-current, Digital Command Control, and DCS layouts. We ran the locomotive on our staff model railroad with the CVP EasyDCC system.
