The BC4ü Bay 14 was a bogie through car with side aisle, the sheet no. 132 for the K.Bay.Sts.B. was built for use in international express train traffic.

procurement

As the third generation of the Bavarian express train wagons, a total of 169 wagons of the types AB4ü , ABC4ü , BC4ü and C4ü were purchased between 1908 and 1924 . To improve running smoothness, these were equipped with the longer Bavarian standard bogies with a 3,500 mm wheelbase.

Whereabouts

Except for one decommissioning (damage?), The wagons were all taken over by the DR. After 1945 three cars can no longer be verified. The wagons were retired from the DB by 1956.

Constructive features

Underframe

The base frame of the connected to the car body underframe was built entirely of wood, which partially - z. B. for the outer side members - was reinforced with screwed angle iron. Wooden profiles were also used for the cross members. This design promised a smoother run for high-quality cars. The wooden cross members to hold the turntable pans were also reinforced with angle iron. Due to the large wheelbase, trusses with adjustable tie rods were added to support the outer longitudinal members. The buffer beams were built entirely from rolled sections. 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

To improve the smoothness of the run, the cars had long bogies of Bavarian design with a wheelbase of 3,500 mm. The frames of the bogies were riveted together from sheet metal and angles. The axles were stored in sliding axle bearings. The wheels had spoked wheel bodies of the Bavarian type 39. The longitudinal springs existing on nine leaves had a length of 1,250 mm with a cross section of 90 mm × 13 mm. Because of the large distance between the bogies, the underframe was supported by a spatial truss in the plane of the outer side members. This could be reproduced. All cars had a handbrake in the closed transition at one end of the car and air brakes of the Westinghouse type . For the transition to other companies, some of the wagons were also equipped with automatic suction air brakes from the HARDY system.

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 smooth and pulled down to the top of the outer side rails. The cars had a barrel roof of southern German design. The roof ends over the drawn-in entrances were rounded.

Furnishing

The interior had a total of eight compartments, three of the second class and four of the third class. These were closed with sliding doors to the side corridor. The compartments of the 2nd class had upholstered seats, those of the 3rd class had wooden slatted benches. The toilets combined with washing facilities were located at both ends of the car . The cars were heated by steam heating . The ventilation took place via roof vent or via the retractable windows. The lighting was done by gas lamps . A large storage container hung on the frame lengthways. From the 1930s onwards, it was converted to electrical lighting. For the transition to Austria and / or Switzerland, the wagons were equipped with appropriate signal supports.

comment

In 1930 a total of three cars were converted to BC4ü Bay 14/30 . Changes were made in the toilet area and the cars received a switch cabinet for the electrics. In addition, the side wall panels were renewed.
