@chasing_steam: Shay No. 5 works its way up the final stretch to Bald Knob at Cass Scenic Railroad. 🚂 FOLLOW CHASING STEAM FOR MORE TRAIN VIDEOS 🚂 You hear the whistle echo through the mountains long before the locomotive comes into view. Then, through the smoke and haze, Shay No. 5 finally emerges, digging into the grade just as these geared logging locomotives were built to do. Have you ever heard a Shay locomotive echo through the mountains? #CassScenicRailroad #ShayLocomotive #SteamTrain #Railfan #TrainVideo
