New generation flat car with 25 tf axle load, 74.5 t of payload capacity and 80 feet loading length.

The flat car is designed to carry heavyweight containers and tank containers with non-hazardous freight with a gross weight of up to 36 t in accordance with local technical specifications. With 4 stationary and 10 movable pins used to secure containers, the flat car is able to carry containers of various size categories: 1AAA, 1AA, 1A, 1AX, 1BBB, 1BB, 1B, 1BX, 1CC, 1C, and 1CX.

Construction design of the flat car provides fatigue strength in the course of the whole 32 years of service life.

Increased terms of between-repairs run which provide for the reduction of the freight car life cycle costs by almost 3 times are a considerable competitive advantage of the freight car of model 13-6903.
