Between 1937 and 1968 the South African Railways placed thirty-four Class NG G16 Garratt articulated steam locomotives with a 2-6-2+2-6-2 wheel arrangement in service on the Avontuur Railway and on the Natal narrow gauge lines.The success of the earlier Class NG G13 narrow gauge Garratts that were introduced by the South African Railways (SAR) in 1927, led to a decision that any additional narrow gauge locomotives would be of the same design.Subsequently thirty-four more 2-6-2+2-6-2 locomotives were built, spread over five orders from three manufacturers over a span of thirty-one years.In 1937 Societe Anonyme John Cockerill of Seraing in Belgium delivered four new 2-6-2+2-6-2 locomotives, numbered 85,86.87 and 88, which were so similar to the older locomotives that they were initially classified as Class NG G13 as well. However, in view of the fact that all the carrying wheels were fitted with roller bearing axle boxes and arranged as pony trucks, compared to the Class NG G13 whose inner carrying wheels were built to the Golsdorf system that allowed the axle some lateral movement, it was soon decided to reclassify them to Class NG G16. These pre-war locomotives, like the earlier Class NG G13 locomotives, were built with riveted coal and water bunkers, and with large radius tops on the water tanks. The Welsh Highland Railway owns four Class NG G16 locomotives, of which one has been used for spares to keep the other three running. These three locomotives are, Cockerill built number 87 (pictured)and Beyer, Peacock built numbers 138 and 143. On the Winter time-table the trains only run from Porthmadog to Beddgelert on Saturday and Sunday.With a 45 minute lay over in Beddgelert before the return journey, so lots of photos...will post a couple more along with some stunning Welsh landscape.......
