What is the different of steel rail standard GOST R 51685-2013 and GOST R 51045-2014?

GOST R 51685-2013 and GOST R 51045-2014 are both Russian standards that specify the requirements for steel rails used in railway tracks. The main difference between these standards is their scope.

GOST R 51685-2013 specifies the requirements for steel rails for general-purpose railway tracks with a track gauge of 1520 mm. It covers rails made of carbon and low-alloyed steel grades, and includes requirements for the chemical composition, mechanical properties, dimensions, surface quality, and inspection of the rails.

On the other hand, GOST R 51045-2014 specifies the requirements for steel rails for the construction of industrial tracks, with a track gauge of 750-1520 mm. This standard also covers rails made of carbon and low-alloyed steel grades, but focuses on specific requirements for the hardness of the rails, as well as for the chemical composition, dimensions, surface quality, and inspection of the rails.

In summary, GOST R 51685-2013 is a general-purpose standard for steel rails used in conventional railway tracks, while GOST R 51045-2014 is a more specific standard for steel rails used in industrial tracks.

GOST R 51685-2013 and GOST R 51045-2014 both specify standards for steel rails used in railway track construction in Russia.

GOST R 51685-2013 specifies four types of rails: Type P, Type K, Type S and Type E. Type P rails are primarily used in high-speed passenger transportation, while Type K rails are used in heavy haul freight traffic. Type S rails are used in areas with heavy traffic loads, and Type E rails are used in the construction of switches and crossings.

GOST R 51045-2014 specifies three types of rails: Type R50, Type R65, and Type R75, which are differentiated based on their weight per meter. Type R50 rails weigh approximately 50 kilograms per meter, Type R65 rails weigh approximately 65 kilograms per meter, and Type R75 rails weigh approximately 75 kilograms per meter. All three types of rails are used in railway track construction and are designed to withstand heavy loads and stress.

GOST R 51685-2013 and GOST R 51045-2014 are Russian standards for steel rails used in railway infrastructure. These standards are typically used in Russia and countries within the Commonwealth of Independent States (CIS), such as Kazakhstan, Belarus, and Ukraine. However, it is also possible for other countries to adopt these standards for their own railway infrastructure.

GOST R 51685-2013 and GOST R 51045-2014 specify requirements for steel rails used in railway tracks, including the technical characteristics of rails, such as their length, weight, and dimensions, as well as their mechanical and physical properties, such as their strength, hardness, and durability.

Specifically, GOST R 51685-2013 provides requirements for rails with a weight of 49 kg/m to 75 kg/m, intended for use on a railway track with a gauge of 1,520 mm or 1,435 mm. Whereas GOST R 51045-2014 is intended for rails weighing from 27 kg/m to 68 kg/m, intended for use on industrial railways and mines with a gauge of 1,067 mm.

These standards also specify the methods for testing rails to ensure that they meet the required standards. The usage of these steel rails is to provide a stable, durable and safe foundation for railway tracks, ensuring reliable and efficient rail transport.
