What is a 136 pound rail?
A 136 pound rail (also known as 136 lb rail, rail 136 lbs, or AREMA 136RE rail) is a heavy-duty steel rail defined by its weight of 136 pounds per yard (≈67.56 kg/m). It is one of the most widely used rail sections in North America and international railway projects, designed for heavy haul freight lines, high-speed railways, and high-traffic corridors. The rail features a robust 136RE rail profile, including a thick head, strong web, and wide base, with a 136RE rail cross section area of approximately 86.7 cm², ensuring excellent load-bearing capacity and durability.
GNEE RAIL provides high-quality 136 pound rail with stable dimensions, consistent performance, and flexible processing options, helping customers achieve reliable track performance and cost-effective solutions.
What Does 136 Pound Rail Mean?
The term "136 pound rail" refers to the rail's weight per unit length. Specifically, it means the rail weighs 136 pounds for every yard (0.9144 meters). In AREMA standards, this is commonly referred to as 136RE rail, where "RE" denotes the standard rail section type used in railway engineering.
Key 136RE Rail Dimensions：
Understanding 136RE rail dimensions is essential for proper track design and installation. Typical values are as follows:
| Profile | Standard | Dimensions mm | Section S | Mass m | ||||
|---|---|---|---|---|---|---|---|---|
| H | B | C | D | E | cm² | kg/m | ||
| American standard | ||||||||
| 136RE (TR68) | AREMA | 185,70 | 152,40 | 74,60 | 49,20 | 17,50 | 85,90 | 67,50 |
Why 136 Pound Rail Is Widely Used?
136-pound rail is widely used because it provides a superior balance of high load-bearing capacity and durability for heavy-haul freight networks, high-speed lines, and industrial applications. Compliant with AREMA standards, its high-strength steel design resists wear and fatigue, making it a reliable, long-lasting standard in modern, high-tonnage North American railways.
Key Reasons for Its Wide Use:
- High Load and Speed Tolerance: Engineered to support heavy axle loads and high-speed freight or passenger trains, 136RE rail is designed to minimize deformation and withstand the intense stresses of modern rail traffic.
- Superior Durability: It is designed to withstand fatigue, providing a longer service life in challenging, high-impact environments.
- Standardized Compatibility: As a widely accepted standard (136 RE) in North America, it fits existing, standardized heavy-haul infrastructure.
- Improved Structural Strength: 136# rail provides greater girder strength compared to lighter sections (like 132#), preventing sagging or premature failure under heavy traffic.
- Wide Base Stability: The rail, often produced with a 6-inch base, offers stability and easy integration with modern fastening systems.
FAQ
1. What is the difference between 136RE rail and 132 lb rail?
The 136RE rail has a higher rail weight and larger cross section area, providing greater load capacity and durability compared to 132 lb rail, making it more suitable for heavy haul applications.
2. What is the cross section area of 136 pound rail?
The 136RE rail cross section area is approximately 86.7 cm², which contributes to its strong bending resistance and long service life.
3. What are the applications of 136 lb rail?
The 136 pound rail is widely used in heavy haul freight railways, high-speed passenger lines, and metro systems where high strength and durability are required.
4. Can 136RE rail be customized?
Yes, GNEE RAIL can provide customized services such as cutting, drilling, and special lengths while maintaining standard 136RE rail dimensions.
5. Why is 136RE rail considered heavy rail?
Because of its high 136RE rail weight and robust rail profile, it can support heavy axle loads and continuous traffic, classifying it as a heavy rail section.
