The Bavarian Post Bay 75 (according to DRG generic conventions) were two-axle mail wagons which, according to sheet no. 118 of the wagon directory from 1897 (sheet no. 187 of the directory from 1913) were built as the second type of the first generation of mail wagons.

history

The transport of mail was also a state monopoly in Bavaria which was managed with horse-drawn carriages. With the advent of the railroad, competition arose from the state. On April 30, 1849, the Ministry of Commerce and Public Works, as the supreme supervisory authority for post and railways, obliged the General Administration of the Royal Posts and Railways with the introduction of "bureux ambulants" for the postal service. With corresponding contracts, all companies - including state companies - were obliged to support the postal service. This meant that the railway company had to procure and provide the appropriate rolling stock at its own expense, while the staff was provided by the postal administration. Until the incorporation of the Bavarian Post Administration into the Reichspost on April 1, 1920, all cars were owned by the Bavarian State Railways.

procurement

The first generation cars were procured between 1861 and 1874 with a total of 116 new cars with car bodies between 7,000 and 7,200 mm, iron side members and Heberlein rapid brakes. This was followed between 1875 and 1882 by a second design according to sheet 187 of the WSV from 1913 with a total of 84 cars.

Constructive features

Underframe

The frame of the car still had a mixed construction of wood and iron. Except for the wooden head sills (buffer girders), all longitudinal and cross connections were made of iron. The outer side members had a double-T shape. As a towing device, the wagons had screw couplings with safety hooks according to VDEV, the drawbar was spring-loaded throughout. The wagons were equipped with rod buffers with an installation length of 650 mm, the buffer plates had a diameter of 370 mm.

drive

The wagons had riveted half-timbered axle brackets made of flat iron of the short, straight design. The axles were stored in split sliding axle bearings. The wheels had spoked wheel bodies and a wheel diameter of 1,014 mm. The suspension consisted of a 9-layer spring 90 mm wide and 1,750 mm long, which were attached to the spring brackets with spring straps.

In addition to the spindle hand brakes in the raised brakeman's cab, all of the cars with the basic equipment had Heberlein quick brakes (see WV of 1879, sketch 75). Westinghouse brakes were already demonstrated for all cars in the WV of 1897 . The brakes worked on all wheels on both sides. The car had the old design of the Bavarian brake linkage with a central lever.

Car body

The car body framework consisted of a wooden frame work. It was clad with sheet metal on the outside and wood on the inside. The side walls were slightly indented on the underside, the end walls straight. The wagons had a flat arched roof. They all had a raised, closed brakeman's cab, which was accessible on both sides and only from the outside. The wagons all had continuous side walkways and stop bars.

The interior was divided into two roughly equal halves by a partition. The packing room was on the side of the brakeman's cab, and the letter sorting room on the opposite side. In the middle of the car there was also the stove that worked towards both halves of the car. There was an upholstered seat on each half of the car.

According to the WV of 1913, toilets were installed in wagons 15 117 and 15 189. In the case of cars 15 124 and 15 137, both the partition wall and all other fixtures except for the oven, washbasin and desk as well as the shelf above them were removed.

Furnishing

The wagons had a stove for heating. The cars were all equipped with a pipe for steam heating . The lighting was carried out by oil lamps, some of the cars by gas. The storage container for the illuminating gas hung on the frame in the longitudinal direction of the car.

According to the WV of 1913, toilets were installed in wagons 15 117 and 15 189. In the case of cars 15 124 and 15 137, both the partition wall and all other fixtures except for the oven, washbasin and desk as well as the shelf above them were removed.

The wagons were given the green paint scheme required for the outside and the inscription Königliche Bahn-Post as property identification .

comment

Not all of the cars were listed in the 1913 directory. Of the original 84 cars, only 46 were left in stock. Some of the cars (a total of 10 pieces) were converted into baggage mail cars (see sheet 211).
