136RE Rail
What is 136RE Rail?
AREMA 136RE rails are a commonly used heavy-duty rail profile, it is also widely known as TR68 rail, which represents the same rail profile under alternative naming conventions. 136RE rails are mostly supplied for railway tracks in mining operations and mainline railways. This rail profile is manufactured strictly to AREMA standards. Each meter of rail weighs 136 pounds, equivalent to approximately 67.4 kg/m. They have been offering excellent durability and load-bearing capacity for numerous railway lines.
Compared with other ordinary steel rails, 136RE rails are more suitable for high hardness, excellent strength, and superior wear resistance, which is essential properties for heavy-haul and long-haul railway systems. They are widely used in the US market and South America, with the advantage of high axle loads and long service life. If you require lighter rails, 115RE rails are your best option.

136 RE Rails Specification
136RE rail steel export from AGICO is made of high-strength, wear-resistant, and corrosion-resistant steel grades, and follows rigorous manufacturing processes and quality control procedures in qualified steel rail factories. Its cross-sectional dimensions are designed to fully meet the requirements of railway transportation, maintaining high precision and stability even under prolonged heavy loads. What’s more, 136RE rail also possesses excellent corrosion resistance, enabling long-term stable operation in harsh environments such as humid and rainy conditions, reducing maintenance costs during the service life.
AGICO shows you the detailed technical info of this specifications: 136re is a tee rail profile manufactured according to AREMA standard, 136 refers to the weight of 136 pounds per yard, enabling it with higher load-bearing capacity and wider range of heavy-duty applications compared to 115RE rails.
- Head Width: 74.61mm. The head width of 136RE American standard rails is increased compared to 115RE. This design helps to distribute the concentrated pressure of the wheels on the rail, further improving the rail's service life.
- Bottom Width: 152.4mm. The wide bottom width provides a more solid support base for the steel rail, enhancing the fit between the rail and sleepers, and maintening the rail stability.
- Rail Height: 185.74mm. The higher rail height design helps to improve the rail's bending strength and torsional resistance, making it better suited for heavy-load transportation.
- Web Thickness: 17.46mm. The increased web thickness significantly improves the track's load-bearing capacity under heavy loads and reduces wear caused by long-term operation.
