Remarks:     To handle the three-mile section of 1 in 15 gradient between Cross Creek and Summit, over the Rimutaka Range, these 'Fell' type locomotives had an 0-4-2 wheel arrangement and four horizontal driving wheels, between the frames, designed to grip a centre rail, thereby providing the extra adhesion needed for the climb. The outside engines drove on to the rear pair of coupled wheels of 32 inches in diameter. The inside cylinders drove four spring-loaded grip wheels of 22 inches diameter. On descent of the incline, powerful hand-operated brakes bore against the centre rail and provided positive control over the speed of the locomotive. Additional brake vans, also equipped with similar braking gear, were interspersed at interval in the train to control descent braking. These locomotives were never required to run at higher speeds than 15 mph anywhere, and on the Rimutaka incline, their usual operating speed was between four and six miles per hour when ascending and about 10 mph when descending The Neilson 'H' Locomotives had Joy valve gear instead of Stephenson, a Belpaire firebox, and a larger grate area than the Avonside built engines and were 2 tons heavier.
