 and had four horizontal driving wheels between the frames, gripping a centre rail and providing the extra adhesion needed for the climb. The outside engines drove the rear pair of coupled wheels of 32" diameter, and the inside cylinders four spring-loaded grip wheels of 22" diameter. On the descent, powerful hand-brakes bore against the centre rail, and brake vans with similar braking gear were interspersed at intervals in the train. The locomotives were never required to run at speeds higher than 15 mph, and their usual operating speed was between four and six mph ascending the incline, about ten mph descending.

Withdrawal

After the Second World War, the locomotives were starting to show their age, and the New Zealand government was looking for a way to cut time between Wellington and the Wairarapa. On 7 May 1951, the contract to construct the 8.8 kilometres (5.5 mi) Rimutaka Tunnel

 was let, which spelled the imminent end of the incline, and the need for the H class.

The last revenue service for the H class was on 29 October 1955, when locomotives 199, 201, 202, 203 and 204 hauled a Carterton Show day excursion train up the incline on the return journey to Wellington. When the Rimutaka Tunnel opened five days later, the engines were put to work dismantling the incline that they had travelled on for 77 years.

All the locomotives were officially withdrawn in March 1956, and all except H 199 were then towed to Silverstream

Over the years, exposure to the elements and vandalism had deteriorated the locomotive's condition. In 1980, the Friends of the Fell Society was formed with the intention of restoring H 199 for static display. Restoration began in 1981, and in 1984, the locomotive was moved into the new Fell Engine Museum
