This set of Railway Bridge and Tunnel Engineering Multiple Choice Questions & Answers (MCQs) focuses on Railway Bridge And Tunnel Engineering Set 1

Q1 | On a Single Rail Track,goods trains loadedwith heavy load material run starting from ‘A’to ‘B’ and then empty wagon run from ‘B’ to ‘A’.The amount of creep in the rails:

  • Will be more in the direction of A to B
  • Will be maximum at the middle of A and B
  • Cannot be determined from the given data
Q2 | A triangle is used for
  • Changing the direction of engine
  • Transferring wagons to and from parallel tracks without shunting
  • Separating all the sidings and shunting lines from main lines
  • Preventing the vehicles from running off the track
Q3 | Heel divergence is
  • Always less than flange-way clearance
  • Equal to flange-way clearance
  • Always greater than flange-way clearance
  • Sometimes greater than flange-way clearance
Q4 | Stretcher bar is provided
  • To permit lateral movement of the tongue rail
  • To maintain the two tongue rails at the exact distance
  • To ensure exact gauge at the toe of the switch as well as the nose of crossing
  • To prevent any vertical movement between the wing rail and nose of crossing

  • Dog spike
  • Rail screw
  • Elastic spike
  • Round spike
Q7 | Flat mild steel bearing plates are used
  • For points and crossings in the lead portion
  • With wooden sleepers at locations where creep is likely to be developed
  • On all joints and curves
