6-axle platform wagon type 622, with the letter marking Samms.
In the 1970s, in the Warsaw Pact, increasingly heavier tanks and other armored vehicles began to be developed for the army. It turned out that they weighed more than 60,000 kg and there were no wagons to transport them. The basic military wagon was the 401Z type wagon, intended for transporting heavy vehicles, for example tanks, which is why it was popularly called a tank wagon. The wagon was developed in 1960 by the Central Design Office of the Rolling Stock Industry for civilian and military use. The wagon consists of two two-axle bogies, a stand, which is a platform, and low sides. The wagon is designed to load goods weighing up to 60,000 kg. Production of type 401Z wagons lasted from 1961 to 1973. A total of 8,280 units were built.
T-T data of the 401Z wagon:
Total length 12.24 m. Empty weight 19,500 kg. Payload: 60,000 kg. O-GP SAB + parking brakes. Two 1XT or 1XTa trolleys. Design speed 100 km/h.
