Tikhvin Freight Car Building Plant’s first hoppers have done its 50,000 km
In the framework of the cooperation agreement with OJSC "Freight One", six hopper cars for transportation of fertilizers produced by Tikhvin Freight Car Building Plant have done its first 50,000 km in the process of exploitation. The rolling stock has demonstrated the compliance with the calculated performance and high reliability.
Under controlled operation of "Freight One" there are hopper cars of model 19-9835 with an axle load of 23.5 ton. From the commencement of works the loading of each car was of the order of 69 tons, depending on the density and volume of the transported substances.
The existing body design of a hopper car, developed in conjunction with a leading North American company Starfire Engineering & Technologies. Inc., provides the car mass reducing and its capacity increasing to ensure the necessary strength and structural integrity, as well as lowering the car gravity center. In order to improve reliability and efficiency in the charging process the design of the boot devices will also be improved.
The hopper car body capacity has no analogues whereon the rail gage 1520 is used and is 101 cubic meter, that enables to carry the entire range of mineral fertilizers with the full use capacity. In addition, the manufactured body can be converted to an effective grain with minimum renovations. While using the carts Barber S-2-R with an axial load of 25 ton the hopper car capacity will be 76 tons, which will allow the rolling stock owner to reduce the rail car fleet needed and save at a rate of 8%.
