⭕ A. Zero
⭕ B. More in direction from Y to X
⭕ C. More in direction from X to Y
⭕ D. None of the above
📚 Explanation:
Creep in rails refers to the longitudinal movement of rails in the track due to repeated traffic loads and braking forces.
🔹 When loaded goods trains move from X to Y and return empty from Y to X, the force exerted on the rails is greater in the X to Y direction.
🔹 This causes more creep in the direction from X to Y as the heavier loads push the rails forward.
🔹 The reverse empty movement exerts lesser force and thus contributes less to creep.

👉 Therefore, the correct answer is: C. More in direction from X to Y
Key Concepts on Rail Creep:
- Creep occurs due to thermal expansion, traffic movement, and braking forces
- More pronounced in direction of heavier or frequent traffic
- Requires regular monitoring and maintenance in railways
- Anchoring and anti-creep devices help control creep
- Observed in both broad and meter gauge tracks
