Description:
Rail profile 45E1 (BS90A) manufactured according European Standard EN 13674-4, mass 45,11 kg per metere
The BS90A rail is another type of rail that falls under the British Standard (BS) rail system. Similar to the BS100A rail, it is commonly used in railway track construction in the United Kingdom and other countries that follow British rail standards.
The BS90A rail is a flat-bottomed rail, which means it has a flat base that rests on the sleepers or ties. It is made of steel and has a standard length of 25 meters or 82 feet. The rail profile has a weight of 45 kilograms per meter, which gives it its name “BS90A.”
This type of rail is designed to provide stability and support to railway tracks, ensuring safe and efficient train operations. The BS90A rail is known for its strength, durability, and resistance to wear and tear. It can withstand heavy loads and high train speeds, making it suitable for various types of trains, including both passenger and freight trains.
The BS90A rail also offers good electrical conductivity, which is crucial for signaling and power transmission in railway systems. It is compatible with different rail fastening systems, allowing for easy installation and maintenance.
The BS90A rail is commonly used in secondary and branch lines, as well as in industrial and mining railways. It provides reliable and efficient transportation, contributing to the overall functioning of the railway network.
In summary, the BS90A rail is an important component of railway infrastructure, offering strength, durability, and electrical conductivity. It is widely used in the British rail system and plays a significant role in ensuring the smooth operation of trains.
