Mozambique Railways No. 101 to 104
In 1923, Henschel delivered ten locomotives to the Mozambique Railways. These were four 4-4-2, four 2-4-2 and two 2-8-2. The Atlantics had the works numbers 19906 to 19910 and were originally numbered 101 to 104 by their operator. They had a wide firebox with a huge grate mounted between the rear driving axle and the trailing axle that was originally designed for burning wood, but was later operated with coal.
They were allocated to the shed at Nampula and operated in northern Mozambique. Later they were renumbered 811 to 814 and fitted with smoke deflectors. Still in operation between Nacala and Lumbo in the eighties, they were likely the last Atlantics in regular service anywhere in the world. 813 survived into the 21st century and there are reports of it being restored to working condition.
