NGR 4-6-2TT Havelock

The NGR 4-6-2TT "Havelock" of 1888 is a South African steam locomotive from the pre-Union era in the Natal Colony.

During 1887 designs for a 2-8-2 Mikado type tank-and-tender locomotive was prepared by the Natal Government Railways. The locomotive was built in the Durban workshops and entered service in 1888, named Havelock, but was later rebuilt to a 4-6-2 Pacific type wheel arrangement. The engine Havelock was the first locomotive to be designed and built in South Africa.^[1]

Design and construction

The designs for a 2-8-2 Mikado type tank-and-tender locomotive was drawn up in 1887 by William Milne, the Locomotive Superintendent of the Natal Government Railways (NGR). It was built in the Durban workshops of the NGR and was not only the first locomotive to be designed and built in South Africa, but also the first in South Africa to have eight-coupled wheels. Only the wheels and axles were obtained from England. Construction began on 26 January 1888 and the locomotive went on its first trial trip during August of that year. It was allocated number 48 and was named Havelock after Sir Arthur Havelock, the Governor of the Colony of Natal from 1886 to 1889.^[1][2]

Characteristics

The engine Havelock was the first tender locomotive in NGR service, a tank-and-tender engine that carried its water in the tender as well as in the side-tanks. It had two boiler-mounted sandboxes and was equipped with both Salter and Ramsbottom safety valves. The leading and trailing carrying wheels were fitted in Webb-type radial axleboxes.^[1]

Service

The first official trip was made from Durban to Pinetown on 7 January 1889, after which the engine Havelock was placed in service on the Durban-Cato Ridge section. Being the pride and joy of the NGR, the engine Havelock was present at several official functions, such as the opening of the line from Ladysmith to Biggarsberg Junction on 12 September 1889 and the turning of the first sod for the Orange Free State branchline at Ladysmith on 7 November 1889.^[2]

"Havelock" as "Hairy Mary", c. 1898

During the South African War the engine Havelock was prepared to see action while serving on armoured trains. Unlike usual practice in such cases, the engine was not equipped with armour plate protection, but was draped in strands of thick hemp rope that covered it from front to back. This earned the locomotive the apt nickname "Hairy Mary" amongst the troops.^[1][2]

Modification

With the introduction of more powerful locomotives, the engine Havelock was relegated to branchline working, for which it was converted to a 4-6-2 Pacific type wheel arrangement since the shorter coupled wheelbase would enable it to negotiate sharper curves. It remained in service on the North Coast line between Durban and Verulam until it was scrapped in 1905.^[1][2]
