This set of Railway Engineering Multiple Choice Questions & Answers (MCQs) focuses on Railway Engineering Set 1
Q1 | 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
Q2 | 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
Q3 | 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
Q4 | Cant deficiency occurs when a vehicle travels around a curve at
- equilibrium speed
- speeds higher than equilibrium speed
- speeds lower than equilibrium speed
- booked speed
Q5 | The type of spike used for fixing chairs of bull headed rails to wooden sleepers is
- dog spike
- rail screw
- elastic spike
- round spike
Q6 | 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
- on all the above
Q7 | Composite sleeper index is the index of
- hardness and strength
- strength and toughness
- toughness and wear resistance
- wear resistance and hardness
Q8 | Staggered joints are generally provided
- on curves

- when two different rail sections are required to be joined
- none of the above
Q9 | Creep is the
- longitudinal movement of rail
- lateral movement of rail
