Drawing of AREMA standard 90RA rail

AREMA standard 90RA rail is a type of rail profile specified by the American Railway Engineering and Maintenance-of-Way Association (아레마) for use in railway systems. AREMA is a professional association that develops recommended practices and standards for the design, 건축, 북미 지역의 철도 인프라 유지 보수.

AREMA standard 90RA rail profile is designed to provide a stable and durable track for heavy-duty railway applications, such as mainline freight and passenger trains. It has a distinctive shape with a broad base and a gradual taper towards the top, providing excellent load-bearing capacity and resistance to wear and fatigue.

The 90RA rail is typically made of high-quality steel and undergoes stringent quality control measures during production to ensure its reliability and performance. The rail must meet specific requirements for hardness, 연성, 및 치수 정확도, as well as various other factors such as surface finish, 직진도, and uniformity of cross-section.

Proper installation and maintenance of AREMA standard 90RA rail are essential for ensuring safe and efficient railway operations. 레일은 트랙 베드에 단단히 고정되어야 하며 마모나 손상의 징후가 있는지 정기적으로 검사해야 합니다. 마모 흔적이 있는지 확인하기 위해 정기적인 검사가 수행됩니다, 변형, 또는 정렬 불량. 감지된 모든 문제는 철도 시스템의 무결성과 기능을 유지하기 위해 수리 또는 교체를 통해 즉시 해결됩니다.

The 90RA rail profile is compatible with various types of railway vehicles, making it a versatile option for heavy-duty railway applications. Its unique design provides a stable and durable track, 소음과 진동을 줄이면서 승객의 편안함을 향상시킵니다.. 또한, the broad base of the rail profile offers superior load-bearing capacity, supporting the weight of even the heaviest trains.

요약하면, AREMA standard 90RA rail is a vital component in railway systems, providing a stable and durable track for heavy-duty railway applications. 견고한 구조와 정밀한 설계로 인해 철도 인프라의 필수적인 부분이 되었습니다, contributing to the safe and efficient movement of people and goods across North America. 적절한 설치 및 유지 보수는 철도 시스템의 장기적인 신뢰성과 성능을 보장하는 데 매우 중요합니다. AREMA standards provide guidelines for ensuring the safety and reliability of railway infrastructure in North America.
