@chasing_steam: Shay No. 5 slows things down for some classic geared steam action at Cass Scenic Railroad 🚂⚙️ Watch the smoke billow from the locomotive’s Radley-Hunter spark arrester before the gears take over in slow motion. Built for steep logging railroads, Shay locomotives combined visible machinery, pulling power, and unmistakable steam atmosphere unlike almost any other train. #shaylocomotive #steamtrain #railfan #cassscenicrailroad #slowmotion
