In the engineering register of the Deutsche Reichsbahn they were listed as the Class CL Bay 14II under Sheet No.
With the growth of the Lokalbahn branch line network in Bavaria, there was a need for suitable coaches for local passenger services.
In total, in the period between 1909 and 1929, 411[1] class BL, BCL, CL, DL and PPostL coaches were procured.
They all had a standard floor plan, open end-platforms with Dixi gates on the steps and gangways protected only by a single iron railing.
Between 1911 and 1914, 36 coaches built to Design Sheet 554 were procured in a total of five batches from the companies of MAN in Nuremberg and Rathgeber in Munich.
The CL coaches only carried 3rd class passengers and had a total of 56 seats and a toilet.
