For a sleeper density of (n+5), the number of sleepers required for constructing a broad gauge railway track of length 650 m is
Answer: 900
Answer: 900
1. Reconnaissance survey
2. Preliminary survey
3. Traffic survey
4. Location survey
The correct sequence in which these surveys are conducted before the alignment of a track is finalised isAnswer: 3,1,2,4
1. They improve the track modulus.
2. They have good scrap value.
3. They render transportation easy.
4. They maintain the gauge quite satisfactorily. Of these statements
Answer: 1 and 4 are correct
1. greater risk
2. higher efficiency
3. avoidance of block instruments
4. higher operating cost Of these statements
Answer: coefficient of friction
i) outer signal
ii) home signal
iii) starter
iv) advanced starter The correct answer is
Answer: (i) and (ii)
i) 2 obtuse angle crossings
ii) 4 obtuse angle crossings
iii) 4 acute angle crossings
iv) 6 acute angle crossings The correct answer is
Answer: (i)and(iv)
i) heel divergence
ii) length of tongue rail
iii) flangeway clearance
iv) throw of switch
The correct answer isAnswer: (i) and (ii)
i) Creep is greater on curves than on tangent railway track,
ii) Creep in new rails is more than that in old rails,
iii) Creep is more on steep gradients than on level track. The correct answer is
Answer: (i)and(ii)
