The 115RE rail, also known as TR57 rail, is a heavy-duty track profile defined by the AREMA (American Railway Engineering and Maintenance-of-Way Association) standards. With a theoretical weight of 56.9 kg/m, the 115RE rail offers exceptional load-bearing capacity, making it a preferred choice for high-demand railway applications.
Designed for high-speed, heavy-haul, and high-density railway lines, the 115RE rail delivers superior performance for both passenger and freight transportation. It is widely used across main lines and major railway hubs in the United States, where durability and strength are critical. Compared to the 100RE rail, the 115RE rail profile offers greater section weight and enhanced resistance to wear, making it ideal for high-intensity heavy-load operations.
115RE rails are manufactured from premium-grade steel to ensure high durability, strength, and resistance to deformation. Glory Rail supplies 115RE rails in standard lengths of 12 m, 18 m, and 25 m, with a T-shaped rail profile for optimal strength and stability. The rail ends can be drilled for fishplate connections, allowing secure joint assembly with adjoining rails.We also provide custom lengths to meet specific engineering requirements.
Below are the 115RE rail dimensions and weight specifications according to the AREMA standard. All rails are manufactured to meet strict tolerance requirements, ensuring compatibility with existing railway systems.
| Type of Rail | Standard | Dimensions mm | Steel Grade | Mass M | |||
| Height | Base Width | Head Width | Web Thickness | kg/m | |||
| 115RE | AREMA | 168,3 | 139,7 | 69,1 | 15,00 | IS/SS | 56,9 |
The 115RE rail is available in two steel grades: IS (high-strength) and SS (standard-strength). Each grade differs in mechanical properties and chemical composition, allowing engineers to choose the most suitable option for specific railway design and load requirements. Mechanical properties and chemical composition are shown in the table below:
| IS | Mechanical Property | Chemical Composition | ||||||||||||
| Yield strength | Tensile strength | Elongation | Hardness | C | Si | Mn | S | P | Cr | Ni | Cu | |||
