136RE rail also be named TR68 (136 RE) AREMA standard freight rail, it is widely used in Americas area, we can produce it by order, the MOQ should be 500 tons. The material can be SS and HH, length can be 39 feet to 25 meters.
136RE rail is a type of steel rail used in railway tracks, primarily in America. The “136RE” designation refers to the weight of the rail, which is approximately 136 pounds per yard (67.4 kg/m). It is classified as a heavy rail and is commonly used for mainline tracks, including both freight and passenger railways.
136RE rail have specific dimensions and profile that conform to industry standards. These rails are typically made from high-strength carbon steel to withstand the heavy loads and stresses imposed by trains. They are installed on either concrete sleepers or wooden ties and secured to the sleepers with various fastening systems, such as clips or spikes.
The exact specifications and properties of 136RE rail may vary slightly depending on the specific manufacturer or region. However, they are designed to provide durability, stability, and smooth operation for trains.
If you have any further questions about 136RE rail or their application, please let me know.
AREA 136RE steel rail is a railway track rail produced according to the standards of the American Railway Engineering and Maintenance of Way Association (AREMA). Here are some basic information about 136RE rail:
1. Material: 136RE rail is made of high-quality carbon steel, which has high strength and hardness.
2. Size: The standard size of the AREA 136RE steel rail is 136 pounds per yard (approximately 68 kilograms per meter), and it also has a specific head shape and contour design to ensure stability and stability during operation.
3. Characteristics: AREA 136RE steel rail has good wear resistance and impact resistance, and can withstand heavy loads and high-speed operation. At the same time, it also has good welding and processing performance, making it easy to install and maintain.
4. Application: 136RE rail is widely used in the railway transportation field in the United States and other countries and regions that use AREMA standards, including trunk railways, mining railways, industrial railways, etc.
Overall, AREA 136RE steel rail is a high-performance railway track rail suitable for various heavy-duty and high-speed railway transportation systems. As a Chinese supplier, we can provide high-quality 136RE rails and other types of railway track products to meet the needs of different customers.

Standard EN 13674 - 1:2003 consists of two main parts:
− qualification test and acceptance tests
Qualification tests are some other tests that were previously carried out, as for example, fracture toughness. Acceptance tests characterize the properties of the prescribed tests, which ensure production of high quality rails, and testing requirements of railway administration.
Quality of rails is based on measured values of hardness, by which they introduced new labels for steel rails.
Qualifying tests
Qualification testing must be conducted at least one in five years and the major
changes in technology, production rails. Additional testing residual stresses are carried
out on all types of steel rails every two year maximum, provided that the longitudinal
strain rate in the rails can amount to up to 250 MPa.
The prescribed qualifying examination is the following:
− fracture toughness
− fatigue crack growth rate
− fatigue testing
− residual stress in rail foot
− variation of centre line
− tensile strength and elongation
− segregation
− other qualification requirements
Acceptance tests
Within acceptance testing is carried out a series of laboratory tests such as:
− chemical composition (the maximum content of the following elements: H, O, Al, V, N and oligo elements)
− microstructure (increasing x 500)
− degree of decarburizing charred layer (allowed up to 0.25 mm)
− purity of steel (especially the presence of oxide)
− macrostructure (Baumann test)
− hardness
− tensile strength
Other acceptance testing rails are:
− dimension tolerances
− criteria (control template)
− inspection requirements / tolerances for to internal quality and surface quality
Internal state is examined ultrasound in a continuous process control, and includes at least 70% of the head and at least 60% web.
- Standard of UIC 860 V: 1996 - prescribed four types pearlite steel rails in the range of tensile strength from 700 to 1300 MPa.
- Standard EN 13674 - 2003, provides seven types pearlite steel hardness in the range 200 to 390 HBV, types steel in accordance with EN 13674, based on the values of hardness (R 200, R 220, R 260, R 260 Mn, 320 Cr, 350 HT, 350 LHT).
