CGR 3rd Class 4-4-0 1884

The CGR 3rd Class 4-4-0 of 1884 is a South African steam locomotive from the pre-Union era in the Cape Colony.

In 1884 the Cape Government Railways placed two experimental 3rd Class tender locomotives with a 4-4-0 American type wheel arrangement in service. They were designed by the Cape Eastern System to be able to use the low-grade local coal with its high content of incombustible matter.^[1][2]

Stormberg coalfields

The extension of the Cape Government Railways (CGR) Eastern System's line from Queenstown reached Sterkstroom in 1883 and passed through the Stormberg coalfields where the Molteno and Cyphergat mines were operating.^[1][3]

While the Colonial coal was much cheaper than imported coal, it had a non-combustable content of as high as 29%, which led to difficulties when used in locomotives since it frequently caused train delays to allow the firemen to clear the grate of clinker and ash. In attempts to overcome the problem, J.D. Tilney, the Eastern System's Locomotive Superintendent, carried out many experiments on some of the 4th Class 4-6-0TT locomotives that had entered service on the Eastern System in 1880, chief of which involved modifying the boilers and frames to accommodate oscillating firebars and larger fireboxes.^[1]

Manufacturer

Based on the results of Tilney's experiments, complete sets of drawings for a 4-4-0 American type tender passenger locomotive as well as a 4-6-0 Tenwheeler type tank-and-tender goods locomotive were prepared at the CGR's Salt River shops in 1882 and submitted to Neilson and Company for the construction of two 4-4-0 and four 4-6-0 locomotives.^[1][2]

The 4-4-0 locomotives entered service in 1884, numbered E53 and E54 for the Eastern System. No. E54 was delivered to the Eastern system, but no. E53 was initially delivered to the Western System for evaluation and testing by Locomotive Superintendent Thornton.^[1][2]

The design of the two types was also an early attempt at standardisation, since the boilers and tenders and many other parts were made interchangeable. The three-axle tender was unusual since the leading axle was mounted in a rigid frame while the other two were mounted in a bogie. This was the first time that a bogie was used under a tender in South Africa, but also the only time that this tender wheel arrangement was used on the CGR. This peculiar tender wheel arrangement appeared in South Africa on only one other occasion, eighteen years later on the Baldwin-built Zululand Railway Company 2-6-0 locomotive in Natal.^[1]

Service

The locomotives gave good results in service, but were difficult to fire due to their very long and narrow grates. When better quality coal that was more suitable for use in the standard locomotives began to become available from the coalfields in Natal, no more locomotives of this experimental design were ordered.^[1]

Both locomotives were renumbered by 1886, when the system number prefixes were done away with and the Eastern System's locomotives were renumbered into the 600 number range. No. E53 became no. 645 and no. E54 became no. 646. Neither entered South African Railways service since both were withdrawn from CGR service between 1900 and 1910.^[1][2]

The pictures below are possibly the only ones in existence of the locomotive in service.^[4]
