Class 19B #1412 named Bailey (coal burner) was manufactured in 1930 in Germany and was virtually identical to the Class 19 locomotives with the exception of the wheelbase of the front bogie. It also has a 4-8-2 Mountain-type wheel arrangement and a Watson Standard boiler.
In 1930, the South African Railways placed fourteen Class 19B steam locomotives with a 4-8-2 Mountain type wheel arrangement in service. One of them was later reboilered and reclassified to Class 19BR.
The South African Class 19B, numbered in the range from 1401 to 1414, was a later model of the original Class 19 which had been designed in 1928 under the supervision of Colonel F.R. Collins DSO, Chief Mechanical Engineer (CME) of the SAR from 1922 to 1929.
