The Palatine AB4ü from 1907 are four-axle compartment wagons with side aisles for express trains based on sample sheet 015 from the wagon register from 1913 for the Palatinate network of the Royal Bavarian Railways .

History / procurement

With the increased number of supraregional passenger trains and express trains in the first decade after 1900, the Palatinate Railways also had to grapple with being able to provide appropriate types of wagons for these types of train. In particular, the wagon compensation agreed with the neighboring railways prompted the Pfalzbahn to also procure wagons for upscale passenger train traffic. As a result, a total of four cars of this type were purchased in 1907 as 1st and 2nd class cars.

commitment

According to the numbering scheme applicable to the Palatinate Railways, this type of car was procured by the Palatinate Ludwigsbahn. It can therefore be assumed that they were used in the high-quality express trains of the respective routes. This included routes such as Saarbrücken-Landau-Bruchsal-Munich or Saarbrücken-Ludwigshafen-Frankfurt.

Whereabouts

When the Pfalzbahn was incorporated into the Bavarian State Railroad in 1909, these cars were also taken over. In 1920 the cars came to the Reichsbahn's Bavarian Group Administration and were subordinated to the Ludwigshafen directorate. There they received the generic identifier AB4ü Bay 07 . The further route is not known, as the Reichsbahn did not keep separate data for the former Palatinate wagons.

Constructive features

Underframe

The frame consisted of riveted rolled sections. The outer side rails were U-shaped with outward-facing flanges. To support the car body due to the large pivot spacing, a truss frame made of profiles and pillars was installed in the plane of the outer longitudinal beams. As a towing device, the wagons had screw couplings with safety hooks according to VDEV , the drawbar was spring-loaded throughout. The wagons had double-slotted basket buffers with an installation length of 650 mm. The buffer plates had a diameter of 400 mm. These were later partly replaced by case buffers.

drive

To improve the running smoothness, the bogies of the Bavarian design with a long wheelbase of 3,500 mm were used. These had a frame riveted from sheet metal and angles. The axles were stored in sliding axle bearings. The wheels had spoked wheel bodies and a wheel diameter of 1,014 mm. In addition to a handbrake, two systems of compressed air brakes were used, which enabled the transition to neighboring railway companies.

Car body

The frame of the car body consisted of wooden studs, planked with wood on the inside and sheet metal on the outside. The straight side walls were pulled down over the outer longitudinal beams. At both ends of the car there were passages closed by bellows, the entrance doors were retracted. The wagons had a flat barrel roof on which there was a filling opening for the water tanks of the toilets at both ends of the wagon.

The car had a toilet at both ends and a urinal at one end. The compartments were separated by doors against the side passage. The two compartments of the first class were at one end of the car, the compartments of the second class followed.

Furnishing

The lighting was electric, the generator was a dynamo on a bogie. The electricity was distributed via a buffer battery that hung under the car body . Heating took place via steam heating which was supplied by a continuous steam line.

For ventilation, the cars had windows with metal frames built into the ventilation flaps, similar to those in Prussia or Alsace-Lorraine.

comment

During the renovation in 1930 - as with other Bavarian express train passenger cars of the same generation - the toilets and the electrical system were modified.
