AREMA Rail Anchors | Railway Fasteners

AREMA Rail Anchors are essential components in rail track fastening systems, designed to secure rails to ties (sleepers) and prevent longitudinal rail movement. The American Railway Engineering and Maintenance-of-Way Association (AREMA) is a standard-setting body that defines the specifications and requirements for components used in rail infrastructure. AREMA rail anchors are built to these specifications to ensure that rail alignment, track gauge, and overall track stability are maintained under various stresses, including dynamic loads, vibrations, and thermal expansion.

Design and Specifications

AREMA standards for rail anchors specify requirements for materials, heat treatment, and minimum holding power. 

• Material: Typically manufactured from heat-treated spring steel(1060 steel) or equivalent materials, such as 60Si2MnA or 65 Manganese, to provide the necessary elasticity and durability.

• Holding Power: Anchors meeting AREMA specifications provide superior holding power, often exceeding the minimum 6,000 lb requirement (some superior products can offer over 9,000 lb min).

• Types: The most common types are "drive-on" anchors, designed to be installed using a standard spike maul or automated equipment.

• Compatibility: They are made for specific rail sections (e.g., 100RE, 115RE, 136RE) based on the rail's weight and base width. 

Installation

General rules for installation specify that the anchor should be firmly fixed to the rail base and fully support the tie face. Rail anchors should be installed on the gauge side of the rail base and positioned against the same tie face on opposite rails. 

The AREMA rail anchor is an essential component in maintaining track stability, safety, and performance across various rail systems. Its ability to prevent longitudinal rail movement, maintain track gauge, and withstand dynamic forces makes it crucial for freight, passenger, and industrial rail systems. Designed for durability and resilience, AREMA rail anchors offer an effective, cost-efficient solution to ensure long-term stability and safety in the railway track infrastructure.
