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.
