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 B to A
- 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
Q5 | 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
Q6 | The type of spike used for fixing chairs of bull headed rails to wooden sleepers is
- 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
- On all the above
Q8 | Composite sleeper index is the index of
- Hardness and strength
- Strength and toughness
- Toughness and wear resistance
- Wear resistance and hardness
Q9 | Staggered joints are generally provided
