How to install a cast iron rail shoulder?

Preparation:

Clean the rail base and sleeper surface to remove rust, debris, or old fasteners.

Check the rail shoulder for defects (cracks, warping) before installation.

Positioning:

Place the cast iron rail shoulder snugly against the rail foot, ensuring proper alignment with the rail gauge.

Verify that the shoulder fits securely without gaps (use a feeler gauge for precision).

Fastening:

Insert shoulder bolts or clips (e.g., Pandrol e-clips, SKL-12) to hold the shoulder in place.

Torque bolts to 200–250 Nm (manufacturer specifications may vary).

Final Inspection:

Ensure the rail shoulder provides firm lateral support to prevent rail roll.

Check for proper contact between the shoulder and rail base to avoid uneven load distribution.

Tools Required:
Torque wrench

Rail gauge

Feeler gauge

Impact wrench (for large-scale installations)
