What is 136RE Rail?
The 136RE rail is a heavy-duty steel rail profile designed under the standards of the American Railway Engineering and Maintenance-of-Way Association (AREMA). But what exactly does 136RE rail means in the industry?
It signifies a rail weighing approximately 136 lbs per yard (136 lb rail), specifically engineered for Class I railroads, high-stress curves, and heavy-haul freight lines. Internationally, this profile is also known as the TR68 rail, representing one of the most reliable standards in modern track engineering.
Technical Specifications: 136RE Rail Dimensions & Profile
To ensure precise engineering integration, understanding the 136re rail dimensions and 136re rail profile is critical. The AREMA 136RE rail is designed to balance vertical stiffness with lateral stability.
136re rail dimensions:
| 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 |
The 136re rail section is characterized by a thicker web and head compared to lighter alternatives like the 115RE, making the 136RE heavy rail the preferred choice for lines carrying over 100 million gross tons (MGT) annually.
Why Choose GNEE RAIL for AREMA 136RE Rail?
At GNEE RAIL, our professional expertise in manufacturing 136 RE steel rail ensures that every track inch meets the rigorous demands of the North American market.
1. Advanced Head-Hardened Technology
Our 136RE rail undergoes a specialized head-hardening process. This significantly increases the service life of the 136 pound rail in sharp curves and heavy braking zones, reducing the frequency of rail replacement.
2. Precision Manufacturing
From the initial 136re rail cross section area design to the final rolling, we utilize automated cooling and straightening beds. Every 136 lb rail is tested for ultrasonic defects to ensure internal structural integrity, meeting or exceeding AREMA 136RE standards.
3. Comprehensive Railway Solutions
Beyond the rail 136 lbs supply, we provide matching fastening systems, including tie plates, E-clips, and joint bars specifically designed for the 136re rail dimensions.
FAQ
Q: Is 136RE rail compatible with high-speed passenger lines?
A: While primarily used for heavy freight, the 136RE rail section is frequently utilized in mixed-use high-speed corridors because its 136re rail height and stiffness provide excellent track geometry retention.
Q: What is the standard length for 136RE heavy rail delivery?
A: GNEE RAIL supplies the 136RE rail in standard 39ft or 80ft lengths, with custom continuous welded rail (CWR) options available upon request.
Q: How does the TR68 designation relate to 136RE?
A: TR68 is the metric-equivalent designation often used in international tenders to describe the same 136 lb rail profile.
GNEE RAIL ensures that all 136RE rail shipments are accompanied by MTC (Mill Test Certificates) proving compliance with AREMA 136RE rail chemistry and mechanical requirements. Whether you are upgrading a transit line or constructing a new mining spur, our logistics team handles the complexities of transporting 136RE heavy rail to your site, ensuring the 136re rail profile remains undamaged during transit.
