The engines had an external frame with outside drive and valve gear. They had the smallest wheel diameter of any locomotive of this type in the whole of Germany. Between 1869 and 1871 all the engines were rebuilt in Regensburg and were given a 1 B axle arrangement. They were then given locomotive numbers 1081–1092.

The second series of this class was built to a Stephenson design. They did not differ greatly in terms of boiler and driving gear from the locomotives of the first series. These engines were also converted in Regensburg between 1870 and 1871 to vehicles with a 1B axle formula. In addition the boiler overpressure was raised from 6 to 10 bar. They were then given locomotive numbers 1069–1080.

Tender

Both series were equipped with 3 T 7 tenders.
