The Palatine AB4ü from 1911 are four-axle compartment wagons with side aisles for express trains based on sample sheet 016 from the wagon status register from 1913 for the Palatinate network of the Royal Bavarian Railways . The Bavarian State Railways had comparable wagons with the AB4ü according to sheet 080 (according to the KBSt.E. wagon register from 1913), which were built between 1908 and 1912.

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 6 cars of this type were procured in 1911 as 1st and 2nd class cars for cross-border use.

commitment

According to the numbering scheme applicable to the Palatinate Railways, this type of car was procured by the Palatinate Northern Railway . It can therefore be assumed that they were used in the high-quality express trains of the respective routes. According to the directory of all express and express trains in the Palatinate network of K.Bay.Sts.B. from May 1910 z. For example, on the routes of the Palatinate Northern Railway and Maximiliansbahn Bad Münster – Hochspeyer – Neustadt – Weißenburg high-quality express trains such as the D 108 (Dortmund – Cologne – Bad Münster – Basel) or the D 161 (Milan – Basel – Neustadt – Bad Münster – Holland) ).

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 11 . 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 foreign railways ( French Northern Railway , Switzerland and Italy ).

Car body

The frame of the car body consisted of wooden studs, planked with wood on the inside and sheet metal on the outside. At both ends of the car there were passages closed by bellows, the entrance doors were retracted. The wagons had a flat barrel roof. The car had a toilet and a side passage at both ends of the car. The two compartments of the first class were at one end of the car, the compartments of the second class followed. The lighting was done with gas light bulbs. The heating took place via steam.

Furnishing

The lighting was done by gas lamps. The associated supply container was attached to the chassis in the longitudinal direction of the car. 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 - modifications were made to the toilets and the electrical system, lighting, etc.
