Data from WilliamBay, Danmarks Damplokomotiver (1977). Works numbers were 234-235 in 1868 and 249-250 in 1873.
In 1852, English entrepreneur Samuel Morton Peto gained the concession to build the Flensburg-Husum-Tönninger Railway Company (FHTE) to link Tonning on the North Sea with the Baltic Sea. Not long after it opened its main east-west line, however, it suffered from changes in the customs regulations that had hampered seagoing traffic in the Baltic.
By the time this quartet of six-wheelers entered service in 1868, the system had been taken over by Prussia as part of the settlement of the Prussia-Danish War. Now called the Schleswig Railway, it was now redirected to serve North-South requirements.
The engines remained in service on the SE line for several decades, the first being withdrawn in 1891 and the last in 1905.
