FAQs on Geometric Design of Railway Tracks Video Lecture - Civil Engineering Optional Notes for UPSC

1. What is the significance of geometric design in railway tracks?
Ans. Geometric design in railway tracks plays a crucial role in ensuring smooth and safe operation of trains. It involves factors like alignment, curvature, gradients, and superelevation which are designed to maintain stability and reduce wear and tear on the tracks.
2. How does alignment affect the performance of railway tracks?
Ans. Alignment refers to the straightness or curvature of the track. Proper alignment ensures that trains can travel at high speeds without excessive wear on the wheels and tracks. It also helps in reducing the risk of derailment.
3. What is the purpose of superelevation in railway track design?
Ans. Superelevation is the banking of the track on curves to counteract the centrifugal force experienced by trains. It helps in maintaining stability and allows trains to negotiate curves at higher speeds safely.
4. How do engineers determine the optimal gradient for railway tracks?
Ans. The gradient of a railway track is determined based on factors like the type of train, speed requirements, and terrain conditions. Engineers calculate the optimal gradient to ensure efficient operation and minimal strain on locomotives.
5. Why is proper maintenance of geometric design essential for railway tracks?
Ans. Proper maintenance of geometric design is essential for ensuring the safety, efficiency, and longevity of railway tracks. Regular inspections and repairs help in preventing accidents, reducing operational costs, and improving overall performance.
