Introduce the railway steel rails of AREMA standard

AREMA (American Railway Engineering and Maintenance-of-Way Association) has several railway rail standards, including the following:

AREMA Manual for Railway Engineering, Chapter 4 - Rails

AREMA Manual for Railway Engineering, Chapter 15 - Steel Structures

AREMA Manual for Railway Engineering, Chapter 16 - Concrete Structures

These standards cover various aspects of railway rails, such as dimensions, material properties, testing procedures, and installation requirements.

AREMA standard for railway rails includes several types of steel rails, which are classified based on their weight per yard (or meter) and the type of steel used. The most common types of steel rails specified by AREMA are:

115 RE rail: This is a standard rail with a weight of 115 pounds per yard (57.1 kg/m). It is made of carbon steel and is commonly used in mainline tracks.

136 RE rail: This is a heavier rail with a weight of 136 pounds per yard (67.4 kg/m). It is also made of carbon steel and is used in high-traffic areas, such as curves and turnouts.

141 RE rail: This is a heavier rail with a weight of 141 pounds per yard (69.8 kg/m). It is made of high-strength alloy steel and is used in high-speed and heavy-haul applications.

Other types of steel rails specified by AREMA include 100 RE, 132 RE, and 175 LB crane rail, among others. 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 North America, particularly in the United States and Canada. However, it may also be used in other parts of the world where American standards are adopted for railway infrastructure.

The installation of rails in accordance with AREMA standards requires a specific process. Here are the general steps involved in installing rails according to AREMA guidelines:

Prepare the site: The site must be cleared of any debris or obstructions that might interfere with the installation process.

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