Development
As Bavaria's network of ''Lokalbahn'' railways grew so did the requirement for suitable coaches for local passenger transport. Because the only motive power available wereProcurement
Between 1905 and 1911 a total of 281 wagons of classes ''BL'', ''BCL'', ''CL'' and ''PPostL'' were procured, all of which - except for the wagons of Class ''PPostL'' - had a uniform floor plan, open platforms at each end with Dixi gates on the steps and gangways only protected by a single iron railing. Large window panes were fitted instead of the composite windows that had been usual up to that point. They are sometimes referred to as 'the shorts' or 'the short ones' (''Die Kurze''). Because the construction of individual mail or luggage vans on the lightly used ''Lokalbahn'' routes was too expensive and unnecessary, between 1905 and 1911 87 combined mail/luggage vans were procured, of which 79 were of the type PwPost Bay 06 built to Design Sheet 606. They were delivered in eight batches by the firms ofCareer
Of the original 79 vans, by 1940 five had been retired. A total of 44 were taken over by the DB, who retired them by 1963. As early as 1932 eight vans were converted into PwL Bay 06/32 by the removal of the mail compartment; another nine vans were converted in the years after 1945.Design features
Undercarriage
The underframe of the van was made entirely of rivetted steel beams. The outer longitudinal bars had U-profiles with outward facing flanges. The crossbars were also made of U-beams and were not cranked. The vans were fitted with VDEVRunning gear
The vans had axle boxes of a short, straight design made of rivetted sheet and angled steel. The axles were housed in plain bearing axle boxes. The vans ran on Bavarian Type 37 spoked wheels. In addition to a screw brake there were through air brakes of the Westinghouse type.Body
The frame of the van body consisted of wooden posts and beams reinforced by steel straps. The walls were clad with sheet steel externally and wood internally. The side and end walls were straight; the doors inset. The gently curved barrel roof was more rounded at the edges, transitioning smoothly into the side walls but extending like a hood over the gangway. This gangway enabled access to the van from the rest of the train. On both sides there were 1,500 mm wide sliding doors with windows that acted as the loading doors to the luggage compartment. The gangways at the ends were only to be used by railway staff. In 1932 eight vans were converted into pure luggage vans. They were designated as class PwL Bay 06/32. A further nine were also converted to luggage vans after 1945. They were reclassified as PwL Bay 06/xx.Facilities
The van body was divided into a mail compartment and a luggage compartment. These compartments were accessible to one another by a central door. The van was lit with paraffin lamps. In the 1930s they were converted to electric lighting. Steam provided the heating. Ventilation was achieved with static ventilators in the roof.See also
