136RE Rail Dimensions

The 136RE rail, also known as AREMA 136RE rail, 136 lb rail, or 136 pound rail, is a heavy-duty steel rail designed for high-load and high-speed railway lines. It is widely used in freight corridors, passenger lines, and urban transit systems requiring superior load-bearing capacity.

 

GNEE RAIL provides high-quality 136RE steel rail with consistent 136RE rail dimensions, precise 136RE rail cross section area, and reliable mechanical properties. With controlled production and technical support, GNEE RAIL helps customers ensure optimal track performance and long-term cost efficiency.

 

136RE Rail Dimensions

 

136RE (also known as TR68) is a heavy-duty ARA-A/AREMA standard rail with a height of 185.74 mm (7-5/16"), base width of 152.4 mm (6"), and head width of 74.61 mm (2-15/16"). It features a web thickness of 17.46 mm and weighs approximately 67.41 kg/m (136 lbs/yd). It is commonly used for heavy-haul freight lines.

Key Size and Performance Advantages of 136RE Rail:

 

136 lb/yd (67.5 kg/m) AREMA rail offers superior structural strength, increased load-bearing capacity, and enhanced durability for heavy-haul, high-speed mainlines and industrial applications.

 

• Higher Structural Integrity: The 136RE profile (often known as TR68) features a taller profile (185.74 mm or ~7-5/16 inches) compared to lighter rail, which improves bending strength and torsional resistance, reducing deformation under heavy loads.

 

• Enhanced Load Distribution: The base width of 152.4 mm (6 inches) provides a stable, wide footprint that improves stability on sleepers.

 

 

• Greater Wear Resistance: The thicker web (17.46 mm) and optimized head profile offer improved durability against high-impact and wear, making it ideal for high-tonnage freight traffic.

 

• Improved Maintenance Cycles: The 136 lb rail provides higher rigidity, resulting in less damage to rail components, lower maintenance costs, and reduced noise and vibration.

 

• Standardization: As an AREMA standard rail, the 136RE (67.5 kg/m) is designed for easy integration into existing heavy-haul North American rail infrastructure.

 

Key Applications of 136RE Heavy Rail

 

Due to its massive cross-section and high weight, the 136RE heavy rail is deployed in demanding environments:

 

Frequently Asked Questions

 

Q: What is the standard length of the 136RE rail available for shipping?

A: Typically, we provide these rails in standard lengths of 39 feet, 40 feet, and 80 feet. However, we can cut and drill the rails to your customized lengths to perfectly match your specific joint or continuous welded rail (CWR) requirements.

 

Q: What is the difference between 136RE and 115RE rails?

A: The main differences lie in weight, dimensions, and load capacity. While the 115RE weighs 114.7 lbs/yd and is suitable for moderate traffic, the 136RE weighs 136.2 lbs/yd and has a thicker web and wider head, making it the superior choice for extremely heavy freight and high-traffic mainlines.

 

Q: Can you provide the matching fastening systems for this rail?

A: Yes, ensuring track stability requires the right accessories. We provide fully compatible track components for the 136RE profile, including AREMA standard joint bars (fishplates), heavy-duty tie plates, rail clips, and track spikes.

 

GNEE RAIL focuses on delivering stable 136re rail specification, with strict control over 136lb rail dimensions, cross section accuracy, and mechanical performance. Flexible processing options such as cutting, drilling, and matching fastening systems help adapt to different railway applications.
