TR50 steel rail is a type of steel rail widely used in railway tracks. It is designed to meet specific requirements and specifications set forth by the industry-standard ASTM A759.

The designation “TR50” refers to the rail’s specific profile and weight. The “TR” stands for “Tee Rail,” indicating its T-shaped cross-section, while the number “50” represents the weight of the rail in kilogram per meter, which is approximately 50 kg.

TR50 rail is manufactured using high-quality steel and undergoes stringent manufacturing processes to ensure its strength, durability, and performance. It is designed to support the weight of trains and withstand the dynamic forces exerted during operation.

ASTM A759 is the standard specification for carbon steel crane rails, tram rails, and switch rails. This standard outlines the chemical composition, mechanical properties, and dimensional tolerances for TR50 rail.

Proper installation of TR50 rail is crucial for safe and efficient railway operations. Rail fastening systems, such as clips, pads, and bolts, are used to secure the rail to the track bed, ensuring proper alignment and stability.

Regular inspections are conducted to detect any signs of wear, deformation, or misalignment. Timely maintenance and repair are essential to ensure the long-term performance and safety of the rail system.

TR50 rail offers excellent dimensional accuracy, straightness, and uniformity. These characteristics contribute to smooth train movement, reducing noise and vibration.

The rail’s sturdy construction and precise design provide durability and resistance to wear, ensuring reliable performance even under demanding operational conditions. This promotes safe and efficient transportation along the rail line.

TR50 rail finds applications in various railway systems, including industrial cranes, tram tracks, and specialized track sections. Its strength and stability make it suitable for supporting heavy loads and facilitating smooth train operations.

In summary, TR50 steel rail adheres to the ASTM A759 standard and is widely used in railway tracks. It is designed to meet specific requirements for strength, durability, and performance. Proper installation, regular inspections, and maintenance are crucial for ensuring the rail’s long-term performance and safety in railway operations. TR50 rail offers excellent dimensional accuracy, durability, and resistance to wear, making it suitable for a range of railway applications.

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).
