Data from [], last accessed 19 January 2017, (First viewed August 2002). The oddities of later numbering gave the earlier four engines (works #865-868) numbers 21-24, while the 1883 trio (works #1067-1069) bore 18-20.
1889-1893 saw the installation of Westinghouse airbrakes. The six that remained in service in 1901 received a slightly larger boiler of 1,404 sq ft with a firebox area of 81.76 sq ft (7.6 sq m) -- it held 182 tubes. Of the 1874 group, 21 was scrapped in 1896, the other three in 1905. 18 followed in 1906, but the other two endured until 1913.

This stray, single 2-4-0 was of a slightly earlier vintage than the Karlsruhe-built engines. Was she a trial horse? In any case, she persisted until 1914.
