Creep is a phenomenon of

Explanation:

Creep

• Creep refers to the gradual longitudinal movement of rails in the direction of traffic or opposite to it.

• It happens slowly over time due to repeated train loads, braking forces, and temperature variations.

• Creep affects the gauge, alignment, and safety of the track if not controlled.

Additional Information

Causes of Creep

• Dynamic loads from moving trains causing the rails to expand and contract.

• Braking forces applied on descending gradients.

• Temperature changes leading to expansion and contraction of rails.

• Poor fastening system or inadequate ballast support.

Effects of Creep

• Misalignment of track.

• Difficulty in maintaining correct gauge and level.

• Damage to joints, sleepers, and fasteners.

• Potential safety risks if left unaddressed.

Control of Creep

• Anchoring rails properly with anti-creepers.

• Using well-compacted ballast.

• Ensuring correct laying and maintenance practices.
