What is the meaning of 52 kg rail?

What is the meaning of 52 kg rail?

The Indian Railways designed the 52 kg/m weight section in 1959 to meet the requirements of heavier and faster traffic at that time. The railway is proposed for use on all BG main lines with future speeds up to 130 km/h and traffic density of 20 to 25 GMT. Its cross-sectional area is 6615 square millimeters

The 52kg rail is suitable for Trolley, Gantry, Overhead Cranes, Railway Siding, Rail Pole.

GNEE RAIL can provide 52kg rail, 60kg rail, etc.

Compatibility of 52 kg Rail Dimensions with Rail Clips

The fastening system is what anchors the rail to the sleeper, and its design is intrinsically linked to the rail's profile. Rail clips must fit the rail base perfectly to apply the correct clamping force (toe load), which is essential for maintaining gauge, preventing rail creep, and absorbing vibrations.

Elastic Rail Clip Systems

• Modern track construction almost exclusively uses elastic rail clips. These systems are far superior to older rigid fastenings like dog spikes. The 52 kg rail, with its 136.00 mm base width, is compatible with several types of elastic clip systems.

• Pandrol-Style Clips: Clips like the Pandrol E-Clip or PR-Clip are widely used. These clips are driven into a cast-iron shoulder that is embedded in a concrete sleeper. The clip's geometry is designed so that when installed, it exerts a constant clamping force on the rail's base flange.

• Vossloh SKL Tension Clamps: Another common system is the Vossloh SKL clamp (e.g., SKL-12, SKL-14). This system uses a screw spike to tighten a tension clamp against the rail base. The clamp's design ensures that a specific tension is applied, providing the necessary clamping force.

• Insulators and Pads: These systems also require insulators and pads that are dimensionally compatible. The insulator prevents electrical contact between the clip and the rail (for signaling circuits) and must fit the clip's profile. The rail pad, which sits between the rail base and the sleeper, must match the 136.00 mm base width to provide uniform support and dampen vibrations.
