A vertical summit curve on a freight corridor is formed at the intersection of two gradients, +3.0% and −5.0%.

Assume the following:
- Only large-sized trucks are allowed on this corridor
- Design speed = 80 kmph
- Eye height of truck drivers above the road surface = 2.30 m
- Height of object above the road surface for which trucks need to stop = 0.35 m
- Total reaction time of the truck drivers = 2.0 s
- Coefficient of longitudinal friction of the road = 0.36
- Stopping sight distance gets compensated on the gradient

The design length of the summit curve (in meters) to accommodate the stopping sight distance is _____ (rounded off to 2 decimal places).

The number of trains and their corresponding speeds for a curved Broad Gauge section with 437 m radius, are

  • 20 trains travel at a speed of 40 km/hr
  • 15 trains travel at a speed of 50 km/hr
  • 12 trains travel at a speed of 60 km/hr
  • 8 trains travel at a speed of 70 km/hr
  • 3 trains travel at a speed of 80 km/hr
