This is a coal-burning, Heisler-type, geared steam locomotive that pulls modern tourist trains for the Cass Scenic Railroad and the Durbin and Greenbrier Valley Railroad in West Virginia, USA. The engine was built in 1929 and initially used as Meadow River Railroad # 6. It is seen here pulling a tourist passenger train toward Durbin, West Virginia in May 2016.
Heisler-type locomotives had a V-shaped arrangement of cylinders that rotated a centrally-located, longitudinal drive shaft just beneath the engine.
