Other types of steel rails specified by AREMA include 90RA, 100 TENA, 132 TENA, Na 175 LB crane rail, Miongoni mwa wengine. These rails have different weights and are made of different grades of steel to meet specific requirements of various railway applications.

The rail of AREMA is used in railway transportation infrastructure, including rail tracks, switches, crossings, and other components. It is commonly used in North America for both freight and passenger rail systems.

The rail of AREMA is primarily used in South America and North America, Hasa nchini Marekani na Canada. Hata hivyo, it may also be used in other parts of the world where American standards are adopted for railway infrastructure.

Rail clips

Rail anchors

Elastic rail clips

Tension clamps

Rail bolts

Fish plates or splice bars

Tie plates

Rail pads

Screw spikes

Dog spikes

These fasteners are designed to securely attach rails to sleepers or ties, Kuhakikisha utulivu, Usalama, and longevity of the railway systems.

Position the sleepers: The sleepers or ties must be properly aligned and spaced according to the design specifications.

Position the rails: The rails must be laid out on top of the sleepers, ensuring that they are properly aligned and spaced according to the design specifications.

Fix the rail fasteners: Once the rails are in position, the appropriate AREMA-approved rail fasteners must be used to secure the rails to the sleepers.

Tension the rails: The rails must be properly tensioned to ensure that they remain securely attached to the sleepers.

Torque the fasteners: The fasteners must be torqued to the appropriate specifications to ensure that they remain tight and secure.

Test the rails: Hatimaye, the rails must be tested to ensure that they meet the specified tolerances for alignment, gauge, and curvature.
