The Bavarian Post4 Bay 00 , Post4 Bay 01 and Post4 Bay 03 (according to DRG generic conventions ) were listed at the DPB under the category Post 4-b / 15 . They were four-axle bogie mail wagons which, according to sheet no. 201, 200 and 202 of the wagon directory from 1913 were built as the second generation of mail wagons for use in express trains with a box length of 15,000 mm.
development
From 1890, various railway companies - including K.Bay.SB - procured the first four-axle cars for express trains. This also resulted in the need for adequate types of wagons for transporting mail.
procurement
Between 1900 and 1907 a total of 60 four-axle wagons with a uniform, fifteen-meter-long body and divergent equipment were procured. Fifteen of them, built in 1900, belonged to the type according to sheet no. 201. Another four of them, built in 1901, belonged to the type according to sheet no. 200. The remaining thirty-five pieces according to sheet no. 202 were delivered in 1903 and 1907.
Whereabouts
All cars were taken over by the Reichspost. At the DBP, this wagon type was taken over together with the wagons according to sheet no. 198, 199 and 202a still 71 pieces. All cars of these types were taken out of service by around 1965.
Constructive features
Underframe
The frame of the car was completely riveted together from rolled iron profiles and sheet metal. The outer side members had a lying U-shape with outward-facing flanges. The wagons had VDEV screw couplings as the towing device, and 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. The buffers were exchanged for sleeve buffers during renovations in 1929–1932. Due to the long wheelbase of 10,800 mm, the outer side members were reinforced with trusses.
drive
The cars had Bavarian standard bogies of the type with a 2,500 mm wheelbase riveted together from sheet metal and angles. The axles were stored in split sliding axle bearings. The wheels had spoked wheel bodies of Bavarian shape 38. The longitudinal suspension springs had a length of 1,250 mm with a cross section of 90 mm × 13 mm. The transverse suspension springs had a length of 940 mm with a cross section of 90 x 9 mm. The longitudinal suspension springs were 8 layers thick, the transverse suspension springs 6 layers.
The spindle handbrake in the raised brakeman's cab acted on all wheels of both bogies on both sides. The cars were all fitted with Westinghouse brakes.
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 that protruded over the side walls. A skylight structure was placed on the roof, which went directly into the raised brakeman's cab. This was only accessible from the outside on both sides. The wagons all had continuous side walkways and stop bars. The interior was accessed on both sides through two two-part, outward-opening wing doors.
Furnishing
The interior was continuous and without 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 on both halves of the car and the toilet. The differences in the distribution can be seen in the drawings.
In addition to steam heating, the wagons also had an oven heating system. The lighting was initially provided by gas lamps. From 1923 this was converted into electrical lighting.
