Tank car for transportation of of light oil products, model 15-629 (articulated)

With two tanks and three bogies with an axle load of 25 t each increasethe payload capacity to 108 t and the total tank volume to 160 m³.

The length of each section is 12,020 mm and their fittings are designed and placed so as to correspond to those of 12,020 mm long standard tank cars, which enables the tank car to be serviced at standard terminals.

The application of a unique frameless design with solid connections between the tank and the section frames saves metal materials in the production process, and allows for a larger payload.

A revolutionary slack-free coupler ensures an unimpeded passage along straight and curved sections of the track, including those with small radii of 60 to 80 metres.

The car is mounted on bogies with an axle load of 25 t each. The bogies have an integrated break system providing for a safer operation, increasing overhaul mileages and reducing the car’s life-cycle costs.

The breaking system incorporates state-of-the-art breaking devices with an overhaul period of at least eight years, threadless connection fittings for break pipes, and wear-resistant bushes made of formaldehyde resin-based composite material.

The automatic coupling device is equipped with upper and lower catch arrangements, as well as an advanced T2 class draft gear reducing lateral forces to ensure safe transportation of hazardous freight.

Description

The model 15-629 tank car is designed for the transportation of light oil products along main railroads in the 1520 mm gauge area.

The model 15-629 tank car consists of two sections connected by a spherical articulated connector. The design features of the tank car allow for the most efficient possible use of the car’s loading capacity when transporting light oil products with a density of up to 0.84 t/m³, thus solving the problem of underloading when standard four-axle cars are used. The total volume of the two tanks stands at 160 m³, and the loading capacity of the car is 108 t. Together, these specifications ensure the transportation of a quantity of cargo similar to that transported by two standard tanks with 100% axle load usage.

Existing restrictions attributable to the infrastructure of the consignors and consignees were taken into account in the design of the car. The 15-629 tank car’s length over coupler pulling faces is 24,040 mm, while the length of one section is 12,020 mm, which is comparable to the length of a standard four-axle tank. The tank car’s loading and unloading valves and fittings and their placement are coordinated with the spacing of the loading and unloading rack. Thus, the 15-629 tank car can be serviced at standard terminals, including alongside four-axle tank cars. The Tikhvin-produced tank car has a service life of 40 years.
