APSC AE WRD 2019 Questions: Railway Creep

Railway Creep Multiple Choice Question

Question: Creep in railway tracks does not:
(A) Vary at a uniform rate
(B) Continue in one direction
(C) Occur in both rails by equal amount
(D) All of the above

Answer: (D) All of the above

Explanation

The Creep in railway tracks refers to the longitudinal movement of rails within the track structure. This phenomenon is influenced by various factors and does not exhibit consistent behavior. It is defined by its irregularity in rate, direction, and extent across the rails.

Key Characteristics of Creep

Characteristic	Description
Non-uniform Rate	The extent of creep varies due to local factors such as traffic volume, temperature variations, and resistance of track fastenings.
Inconsistent Direction	Creep does not consistently move in one direction, as it may change based on traffic patterns or maintenance activities.
Unequal in Rails	Creep is typically uneven between the two rails due to differences in loading, track conditions, or alignment.

Key Notes

• The Creep is a critical consideration in railway track design and maintenance to ensure track stability and safety.
• Factors like temperature, traffic load, and fastening systems significantly influence the extent and behavior of creep.
• Regular maintenance and monitoring are essential to manage creep and prevent track misalignment.
• Understanding creep is vital for civil engineers working on railway infrastructure projects.

Note: Effective management of creep in railway tracks is essential for maintaining track integrity and ensuring safe and efficient train operations.
