The wheel arrangement is effectively two 2-4-0 locomotives operating back to back, with the boiler and cab suspended between the two power units. Each power unit has two leading wheels on one axle, four powered and coupled driving wheels on two axles and no trailing wheels. A similar wheel arrangement exists for Mallet locomotives, but is referred to as 2-4-4-2 since only the front engine unit can pivot. History This was the second rarest Garratt wheel arrangement. Only five locomotives were constructed to this arrangement, four of which were built by Beyer, Peacock and Company (BP). The four BP locomotives comprised three for the 5ft3in on on São Paulo Railway of Brazil in 1915, and one for the 2ft6in gauge Ceylon Government Railway (CGR) in 1929, the CGR's class H1. One more was built in 1919 by the São Paulo Railway, for its own use on 1000mm on on. Manufacturers +2-4-0+0-4-2 Garratt production list – All manufacturers Gauge Railway Class Works no.
