The PLM had prepared designs for an additional much larger 4-8-zero locomotive by 1913, however it didn’t materialise because of the outbreak of the first World War. In 1906, the NGR modified six of its Class B 4-8-zero Mastodon locomotives, built by NBL in 1904, to Class Altered B locomotives to improve their stability on passenger trains. Hendrie to be used in coal site visitors on the road from Witbank to Germiston, they were the most important non-articulated locomotives in South Africa at the time.

In 1914, ten Class 15 locomotives entered service, built by NBL and designed by Hendrie as large blended visitors locomotives with bigger 57 inches (1,448 millimetres) coupled wheels for use in the Orange Free State, where grades and curvature had been much less extreme than on the coastal sections. As for the fourth driving wheels, adopted Golsdorf axle system (patented by Karl Golsdorf), this make the outer driving wheels able to move laterally by 100 mm.

It was a rude two-cylinder simple enlargement locomotive, also with 1,750 mm (5 ft 9 in) coupled wheels and Vapers barely lighter than its NORTE counterpart, with the primary ones of 1925 at 159.5 tonnes and Vapor STARTER KITS the final ones of 1930 at 163.Forty four tonnes.

In 1909, Vape Disposables the NGR commissioned the primary of thirty Class B (1909) 4-8-2 tender locomotives, additionally recognized because the Hendrie D. Designed by D.A. The first type to be launched, Vape Juices although earlier by only some weeks, Best Vape Juices was the NORTE 4000 class, 4001-4047 in 1925 and 4049-4066 later.The NORTE launched the 4648 just before RENFE was established in 1941. It was an enhanced 4600 type with new designed cylinders after the proposals of André Chapelon. An improved and larger model of his Class 12, Vape Disposables with bigger diameter cylinders and a redesigned boiler that included a combustion chamber, it was superheated and had Walschaerts valve gear and a Belpaire firebox. Like the category 14, Vapor Deals it also had Walschaerts valve gear, a Belpaire firebox and Vape Disposables was superheated, but it had a smaller boiler and smaller cylinders to reduce the axle loading.
