Question 1

To accommodate a 3° curve on a broad guage line, the ruling gradient of 1 in 150 should be downgraded to

Question 2

If the curve lead of a broad-gauge railway turnout is 13.408 meters, the angle of crossing of the turnout is

Question 3

A curve of 1350 m radius is to be set out to connect two tangents. If the design speed is 110 kmph and the rate of change of acceleration is 0.3 m/s3, the shift of the circular curve will be nearly

Question 4

A cross-over occur between two Meter Gauge parallel tracks of same crossing number 1 in 12 with straight intermediate portion between the reverse curves and the distance between the centers of tracks is 3.5 m. If the value of G is 1 m, the intermediate straight distance will be nearly

Question 5

If  is the angle of crossing, then the number of crossing ‘N’ according to isosceles triangle method is given by

Question 6

What would be the admissible gradient for a BG track when the grade resistance coupled with a 4O curve resistance shall equal the resistance due to a ruling gradient of 1 in 200?
