Passenger wagons type 112A of UIC-Y standard.

Type 111A wagons are class 2 cars with 10 compartments and eight seats in each. The car was developed in 1969, but work on it had been ongoing since 1963. Type 112A cars were developed in parallel with type 111A cars. Type 112A is a class 1 car with 9 compartments and 6 seats in each compartment. Both cars have a total length of 24.50 m. Depending on the bogies used, the car is designed for speeds of 140, 160 km/h and 200 km/h. Currently (2024) there are about 1,500 type 111A / 112A cars in service, and many of them have undergone numerous modifications.

Type 112A cars are a variant of type 111A cars, which have 9 compartments inside, and each compartment has 6 individual seats. Thanks to the smaller number of compartments, there is more legroom for seated passengers. The seats are comfortable, with soft upholstery and with the possibility of moving the seat by about 10 cm, which changes the angle of the backrest and the position of the passenger. Additionally, each seat has an additional reading lamp above the passenger’s head, which is mounted to the luggage rack. Externally, the cars have 9 full-size windows instead of 10 windows. Additionally, a gold (yellow) stripe is painted on the car body above the window line, and the number 1 (Class 1) is at the entrance door. Apart from that, the remaining equipment is identical to the 111A type. These wagons were sent to PKP and exported to communist countries.

On the basis of the 112A type wagon, wagons with the letter designation AB9 were also built. These are wagons in which 5 compartments are class 2 (each with 8 seats), and 4 compartments are class 1 (each with 6 seats). In the 1960s, the PKP management assumed that there should be a 1st class wagon in the composition of long-distance trains. Since there were long-distance trains consisting of 3-4 wagons, it was justified to introduce AB9 type wagons.

Type 140A wagons, 60 units, manufactured in 1990-1991, forced air heating.

Trailer bogies.

The wagons were equipped with 4AN type bogies. The two-axle bogie and with the wagon’s service weight of 39,500 kg, worked well. Travel speeds of up to 160 km/h were not a problem and the running was smooth. Initially, an Oerlikon type braking system was used. The brakes are block type. Emergency brake levers were placed in the corridor inside the wagons and in each of the compartments. Cables ran from the emergency brake handle to the Ackerman flap, the opening of which caused a drop in air pressure in the main pipe and stopped the train. Each wagon was also equipped with a manual screw brake, activated from one of the vestibules using a wheel with a crank installed there. Over time, modernized 4ANc type bogies were installed. 4ANc type bogies were installed in some wagons even until 1992. There are also 4ANh and 4ANg versions of the bogies.

In 1979, production of wagons (111Ak) was started, which were equipped with new GP200 type bogies. These bogies already have disc brakes. The GP200 type bogie is designed for speeds of up to 160 km/h, while the GP200N type bogie is designed for speeds of 200 km/h. The abbreviation GP stood for Görlitz-Personenwagen, and the number 200 assumed its maximum speed capabilities, which was not so obvious in the first bogies. The design of the GP200 bogie was created in cooperation between Czechoslovakian wagon manufacturers and the East German VEB Waggonbau Görlitz plant.

In 1983, production of wagons (111Al) was started, which are equipped with 11AN type bogies. The 11AN type bogies are bogies of Polish design, designed for speeds of 200 km/h. The frame of this bogie is open “H”. The first-stage suspension consists of four sets of steel coil springs with a rubber shock absorber. The second-stage suspension consists of two sets of steel coil springs of the “flexicoil” type and metal-rubber shock absorbers. Disc brakes of the OBRPS design and a system from Knorr-Bremse. The prototypes of the bogies were built in 1982.

In 1985, production of wagons (111Ar) equipped with bogies of the 4ANh-6 type was started. The 2-axle bogie is of Polish design of the 4ANh-6 type. The bogie was used for the 111Ar type wagons and is often confused with the GP200 bogies, to which it is similar.

Data T-T type 112A:

Length 24.50 m. Width 2.91 m. Height 4.06 m. Service weight 39,500 kg. Number of seats 54. Speed ​​depending on the bogie used: 140 km/h, 160 km/h, 200 km/h.
