It will get new wheels.
The Darjeeling Himalayan Railway, locally known as the "Toy Train", is a 2 ft (610 mm) narrow gauge railway that runs between New Jalpaiguri and Darjeeling (India). It is still operated by vintage British-built B Class steam locomotives. Operations between Siliguri and Kurseong have been temporarily suspended since 2010 following a Landslide at Tindharia (view photos of the landslide).
