Target entity: K-37 steam locomotives
Context triple: [Cumbres and Toltec Scenic Railroad, hasLocomotiveClass, K-37 steam locomotives]

• A. K-36 steam locomotives
  The K-36 steam locomotives are a class of narrow-gauge, 2-8-2 “Mikado” type engines built for the Denver & Rio Grande Western Railroad, now preserved and operated on heritage lines such as the Cumbres and Toltec Scenic Railroad.
• B. AC-9 articulated steam locomotives
  The AC-9 articulated steam locomotives were a small class of powerful, coal-burning 2-8-8-4 cab-forward-style engines built in the late 1930s for heavy freight service on the Southern Pacific Railroad, notable for being among the last and most distinctive articulated steam locomotives the railroad operated.
• C. Heisler locomotive
  A Heisler locomotive is a type of geared steam locomotive, recognizable by its V‑twin cylinder arrangement and used primarily on logging and industrial railroads for hauling heavy loads over steep, rough track.
• D. B Class steam locomotives
  The B Class steam locomotives are small, narrow-gauge tank engines historically used on the Darjeeling Himalayan Railway, renowned for hauling trains through the steep, winding mountain route in the Indian Himalayas.
• E. Forney locomotive
  The Forney locomotive is a compact 19th-century steam tank locomotive type, notable for its rigid wheelbase and rear-mounted fuel and water tanks, widely used on urban elevated and commuter railways.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.
