The NZR H Class locomotive was first used in New Zealand in 1875. It was designed to run on the Fell system of traction, which uses a smooth center rail laid between the tracks of a normal track system. The fell locomotive has an additional motor to drive the two horizontal pressure applied geared wheels against both sides of the center rail. The Fell engine has a wheel arangement of 0-4-2T with a total adhesive weight of 62 tonnes enabling it to pull a weight of 65 tonnes up a steep grade of 1 in 15 at walking pace. Five engines in one consist was commen, the resulting steam engine sound was amazing. A total of six fell engines were used on the Rimutaka incline for near on eighty years before a tunnel put an end to the operation in 1955. The 1 in 15 incline worked was only 4.8km in length. The operation time being about 20 minutes. One fell engine Number H199 is preserved at Featherston's Fell Museum. The content is for TSR2004. The features are fully animated drive wheels, linkages and center drive gears etc. Animated coal level bunker which is situated on the right rear side of the water tank.
