In Indian Railways, the field survey normally covers a width of :
- A100 m on either side of the track.
- B200 m on either side of the track.Correct
- C300 m on either side of the track.
- D500 m on either side of the track.
Solution
Concept
Width of survey strip
Step-by-step solution
1. A railway field survey (engineering-cum-traffic survey) covers a strip on both sides of the proposed alignment. 2. The usual width taken is about 200 m on either side of the track.
Explanation
Field surveys for railways cover a belt of land on either side of the proposed or existing track so that levels, features and land details can be recorded for alignment decisions.
Why the other options are wrong
100 m is narrower than the usual strip for plans; 300 m and 500 m are wider than a normal field survey strip.
Shortcut
Remember a 200 m strip each side.
Correct answer: B) 200 m on either side of the track.
