0-4-0+0-4-0

ex-Tasmanian Garratt K1 at Snowdon Ranger on the Welsh Highland Railway

In the Whyte notation for the classification of steam locomotives by wheel arrangement, the 0-4-0+0-4-0 is an articulated locomotive, usually of the Garratt type. The wheel arrangement is effectively two 0-4-0 locomotives operating back to back, with the boiler and cab suspended between the two power units. Each power unit has no leading wheels, four powered and coupled driving wheels on two axles, and no trailing wheels. A similar arrangement exists for Fairlie, Mallet and Meyer locomotives, but is referred to as 0-4-4-0.

Other equivalent classifications are:

UIC classification: B+B (also known as German and Italian classifications)
French classification: 020+020
Turkish classification: 22+22
Swiss classification: 2/2+2/2 up to the early 1920s, later 4/4

Overview

Industrial Beyer-Garratt William Francis

The first Garratt locomotive, K1, one of two 2 ft (610 mm) gauge Tasmanian Government Railways K Class locomotives built in 1909, has this wheel arrangement and has been restored to operating condition at the Welsh Highland Railway. This arrangement proved one of the less popular Garratt types, since most Garratt locomotives were larger and more powerful, requiring more pairs of driving wheels to operate within the normal axle load limits, and because leading wheels gave more stability and better tracking to allow faster speeds.^[1]

In total, 34 Garratts of this type were constructed, seven by Garratt patent holder Beyer, Peacock, mostly for industrial use, and 27 by other builders. The largest user of the type was the C.F. Vicinaux du Mayumbe in the Belgian Congo, with twenty locomotives built to a 600 mm (1 ft 11 ⁵⁄₈ in) gauge by St. Leonard in Belgium.^[1]^[2]

In addition to K1 at the Welsh Highland Railway, the industrial Beyer-Garratt William Francis, built in 1937, is preserved at the Bressingham Steam Museum.
