Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 72, pp.384+ . Works number was 58180 in January 1925.
Quelimane is a seaport on the Zambezi river delta and up the coast from both Beira and Maputo. It was described in the 1913 Railway Supplies report as "without question the outlet for the richest and most productive section of Portuguese East Africa." At that time, the railway ran for only 18 miles (29 km) on 30 lb/yard (15 kg/metre) rail up 2% grades and around 200 metre (656 feet) radii on the main line. Plans to extend west to the British colony of Nyasaland (present-day Malawi) border were frustrated by the outbreak of World War I.
This wood-burning Consolidation used the Rushton Improved cabbage stack to suppress sparks and was typical of the small, quite-narrow-gauge locomotive in use all over the world at that time.
