From 1867 a total of 152 examples of this engine were built in Bavaria for the Ostbahn. The five series differed in their dimensions from one another. They had larger grate and heating areas than their predecessor engines, the Class C II. In addition the drive was to the middle axle, so that shorter connecting rods could be used. The locomotives had an Allan valve gear and injectors.

Retirement began after 1905. In 1920, 49 machines were still left. The Reichsbahn recorded 35 of the 38 remaining engines in 1923 and gave them the numbers 53 7835 to 53 7864. However, by 1925 they were no longer on active duty. Three engines went as reparations to the Belgian State Railways.

The locomotives were equipped with 3 T 9 and 3 T 9.5 tenders.
