The Bavarian Class C, later C III, waw a German steam locomotive with the Bavarian Eastern Railway (Bayrischen Ostbahn) and Deutsche Reichsbahn.
From 1867 a total of 152 examples of this engine were built in Bavaria for the Ostbahn.
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 Reichsbahn recorded 35 of the 38 remaining engines in 1923 and gave them the numbers 53 7835 to 53 7864.
