SAFE STOPPING SIGHT DISTANCE AND ECONOMIC DESIGN OF MODERN TRACK

Question-Answer

The design speed for a two-way traffic on a two way lane road is 50 kmph. What is the value of safe stopping sight distance, if co-efficient of friction is 0.37 and reaction time of driver as 2.5 sec?

  • (a) 34.8 m
  • (b) 61.4 m
  • c) 122.8 m
  • (d) 193.5 m


Consider the following statements related to economic design of modern track:

1. Axle loading, possible weight reduction of the rolling stock and increase in number of axles should be rationalized.

2. Rail to sleeper fastenings for different type of sleepers at high speeds should have definite standards.

3. The weight of the sleeper and the rail may not be related to each other. Which of the above statements are correct?

  • (a) 1 and 2 only
  • (b) 2 and 3 only
  • (c) 1 and 3 only
