AT50 Switch rail belong to standard of TB/T 3109-2013, also be named 50AT1 turnout rail, it is used for making turnout or curve railroad, can avoid high side pressure to make the rail break, we can supply the type of 50AT1, 60AT1, 60AT2 and 60TY1, the material is U75V, length is 12m, 12.5m or 25m.

The main advantages of turnout AT rail:
1. The lifting amount of 6mm for ordinary steel rail pointed rails has been cancelled, eliminating the vertical unevenness of trains passing through switches and improving the speed of straight strands passing through switches.
2. The AT rail of the turnout has strong overall integrity and high stiffness, and is not prone to arching and bulging during use, resulting in a small maintenance and repair workload.
3. A 24mm high sliding bed is installed under the AT rail of the turnout, which can buckle the bottom of the basic rail, increasing the stability of the basic rail and the overall integrity of the turnout.
4. Due to the high height of the sliding platform, it can reduce the impact of sand and snow and improve the safety of driving.

The AT50 switch rail is a crucial component in railway systems, specifically designed for use in railroad switches and crossings. Railroad switches, also known as turnouts or points, are mechanical installations that enable trains to transition from one track to another. The switch rail plays a pivotal role in guiding the train wheels along the desired path.

The AT50 switch rail is manufactured to meet stringent standards for strength, durability, and precision. It is typically made of high-quality steel and undergoes meticulous quality control measures during production to ensure its reliability and performance. The unique profile of the AT50 switch rail allows it to withstand heavy loads and the forces exerted by moving trains.

Switch rails are essential for ensuring safe and efficient railway operations. They must be installed and maintained with great attention to detail to guarantee smooth and reliable train movement. Proper alignment and secure fastening of the switch rail are critical to prevent derailments and ensure the safe passage of trains through the switch and crossing areas.

In summary, the AT50 switch rail is a vital component in railway switch and crossing systems, contributing to the safe and efficient movement of trains along different tracks. Its robust construction and precise design make it an essential part of railroad infrastructure, helping to facilitate the seamless operation of railway networks.
