Hopper car on American bogie has received the certificate of conformity
Under the program of creating freight cars of the new generation planned to be produced at Tikhvin Freight Car Building Plant the State Registry of certification on Federal Railway Transport has issued the conformity certificate for the hopper car for mineral fertilizers on bogie Barber S-2-R с with axial load of 23,5 tf.
In the project of creating hopper car was participating leading North American company Starfire Engineering&Technologies. Inc., specialized in engineering of rolling stock for railways of the United States of America and Canada. As a result of implementation of modern approaches to engineering of freight rolling stock, there have been designed the cars with uprated specifications, higher ruggedness and safety.
Structural design of the car body allowed reducing the mass of hopper and increasing its carrying capacity along with providing required ruggedness and safety of construction.
Body space of hopper car is extended on 7 cubic meters to 101 cubic meters along with keeping existing standard length and tare mass that will let increase effective load of the small volume with mineral fertilizers on 6-7%. Extended containment of hopper boxes allowed to reduce center of gravity, and made possible to improve stability of cars from tripping, and extended dimensions of loading doors make car loading process better. Unitized design of hopper car allows using it both with standard home-produced bogie, and with bogie Barber S-2-R with axial load of 23,5.
To recap, Tikhvin Freight Car Building Plant received the conformity certificates for 7 types of freight cars out of 11 planned for production, and also for innovative bogies Barber S-2-R with axial load of 23,5 and 25 tf since before the start-up.
Taking into consideration that running gear design greatly affects useful quality of a freight car and safety of its exploitation, new bogies Barber S-2-R were used for designed cars.
