0-6-0+0-6-0

SAR Class KM Kitson-Meyer number 1600

A 0-6-0+0-6-0 wheel arrangement in the Whyte notation for the classification of steam locomotives was used on Garratt, Meyer and Kitson-Meyer articulated locomotives. The 0-6-0+0-6-0 wheel arrangement is effectively two 0-6-0 locomotives operating back to back. A similar arrangement exists for Mallet and Fairlie steam locomotives, but these are referred to as 0-6-6-0.

In Britain the Whyte notation of wheel arrangement was also often used for the classification of electric and diesel-electric locomotives with side-rod coupled driving wheels.^[1] Other equivalent classifications are:

• UIC classification: C+C (also known as German and Italian classifications)
• French classification: 030+030
• Turkish classification: 33+33
• Swiss classification: 3/3+3/3 up to the early 1920s, later 6/6

Overview

The 0-6-0+0-6-0 wheel arrangement was used on Garratt, Meyer and Kitson-Meyer locomotives.

Garratt locomotives

The 0-6-0+0-6-0 was a rare Garratt model. Beyer, Peacock, the owner of the Garratt patent, only built two of this type to 2 ft 6 in (762 mm) gauge for the Buthidaung-Maungdaw Tramway in Burma. Belgian builder Société Anonyme St. Leonard of Liège constructed thirty-one for the Belgian Congo and two for the roadside tramways of the Belgian SNCV. Hanomag commenced the construction of a single locomotive that was completed by Henschel for the Limburg Tramway in the Netherlands. This last was the only inside-cylinder Garratt.^[2][3]

Kitson-Meyer locomotives

In 1894 Kitson and Company of Leeds built a modified Meyer articulated locomotive of this type for the Anglo-Chilean Nitrate and Railway Company. Thereafter the Kitson-Meyer type was widely used in South America, particularly on the Colombian and Chilean railways. The four that were built for Southern Africa were not successful.^[4]

Usage

Belgian Congo

Belgian Congo type 2MB Garratt no. 112

Between 1913 and 1926 Belgian locomotive builders Société Anonyme St. Leonard of Liège constructed thirty-one 0-6-0+0-6-0 Garratts for the 750 mm (2 ft 5 ¹⁄₂ in) gauge Compagnie du C.F. du Congo in the Belgian Congo. The locomotives were delivered in four batches, one in 1913, twelve in 1920-21, eight in 1924-25 and the last ten in 1925-26.^[3]

South Africa

CGR Kitson-Meyer number 800

The Kitson-Meyer type was tried out by three railways in Southern Africa. In 1903 Kitson persuaded the Cape Government Railways (CGR), the Beira and Mashonaland Railway (B&MR) and the Central South African Railways (CSAR) to try their new 0-6-0+0-6-0 Kitson-Meyer articulated steam locomotive. In 1903 one locomotive was delivered to the CGR and two to the B&MR and, in 1904, one to the CSAR. All three railways found their Kitson-Meyers to be poor steamers and, as built, none of these locomotives had a long service life. The three CGR and B&MR locomotives were all scrapped by 1912. In 1906 the CSAR modified its locomotive by reducing the diameter of the cylinders to bring them within the range of the boiler’s steam generating capacity. While this reduced the locomotive’s tractive effort, it improved its performance sufficiently to allow it to survive in service longer than the other three. In 1912 it was assimilated into the South African Railways (SAR) and designated Class KM.^{[4]:31, 84[5]:69–70, 130–132[6]}

BR Class 13 Hump shunter

United Kingdom

The 0-6-0+0-6-0 configuration was also used on diesel locomotives when British Rail created the Class 13 in 1965. This was done by permanently coupling together two Class 08 0-6-0DE diesel-electric shunters as 'master and slave' (alternatively 'cow and calf') units, the latter with its cab removed.

The modification came about because of a need to provide more powerful shunting locomotives for the Tinsley Marshalling Yard.
