FAQs on Introduction of Track Geometries Video Lecture - Civil Engineering Optional Notes for UPSC

1. What are the different types of track geometries used in railway engineering?
Ans. The different types of track geometries used in railway engineering include straight track, curved track, transition curves, superelevation, and gradient.
2. How does superelevation affect track geometries?
Ans. Superelevation, also known as cant or banking, is the raising of the outer rail of a curve to counteract the effects of centrifugal force. It helps trains navigate curves at higher speeds safely by reducing the likelihood of derailment.
3. What is the purpose of transition curves in track geometries?
Ans. Transition curves are used to gradually transition between straight track and curved track, reducing the abrupt change in curvature and providing a more comfortable ride for passengers while minimizing wear and tear on the track and rolling stock.
4. How do engineers determine the optimal gradient for a particular track geometry?
Ans. Engineers consider factors such as train speed, train weight, and topography to determine the optimal gradient for a particular track geometry. The gradient must be balanced to ensure efficient train operation while also maintaining safety and stability.
5. Why is it important to maintain proper track geometries in railway infrastructure?
Ans. Proper track geometries are essential for ensuring safe and efficient train operations. Maintaining track geometries helps prevent derailments, reduces wear on rolling stock, minimizes maintenance costs, and provides a smoother and more comfortable ride for passengers.
