Question 1

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:
A)Will be more in the direction of B to A
B)Will be more in the direction of A to B
C)Will be maximum at the middle of A and B
D)Cannot be determined from the given data

Accepted Answer

Creep in rails refers to the longitudinal movement of the rail in the track. It is affected by various factors including the load on the rails. When goods trains loaded with heavy materials run from 'A' to 'B', the load on the rails is significantly higher than when empty wagons return from 'B' to 'A'. This increased load when moving from 'A' to 'B' results in greater deformation and stress on the rails, leading to more creep in the direction of 'A' to 'B'.

Question 2

A triangle is used for
A)Changing the direction of engine
B)Transferring wagons to and from parallel tracks without shunting
C)Separating all the sidings and shunting lines from main lines
D)Preventing the vehicles from running off the track

Accepted Answer

A

Question 3

Heel divergence is
A)Always less than flange-way clearance
B)Equal to flange-way clearance
C)Always greater than flange-way clearance
D)Sometimes greater than flange-way clearance

Accepted Answer

Heel divergence is always greater than flange-way clearance to ensure that the wheel flanges can pass through the switch without interference, providing a smooth transition from one track to another.

Question 4

Stretcher bar is provided
A)To permit lateral movement of the tongue rail
B)To maintain the two tongue rails at the exact distance
C)To ensure exact gauge at the toe of the switch as well as the nose of crossing
D)To prevent any vertical movement between the wing rail and nose of crossing

Accepted Answer

Stretcher bars are used to maintain the two tongue rails at the exact distance apart, ensuring the proper alignment and functioning of the switch mechanism in railway tracks.

Question 5

Cant deficiency occurs when a vehicle travels around a curve at
A)Equilibrium speed
B)Speeds higher than equilibrium speed
C)Speeds lower than equilibrium speed
D)Booked speed

Accepted Answer

Cant deficiency occurs when a vehicle travels around a curve at speeds higher than equilibrium speed.

Question 6

The type of spike used for fixing chairs of bull headed rails to wooden sleepers is
A)Dog spike
B)Rail screw
C)Elastic spike
D)Round spike

Accepted Answer

The answer of The type of spike used for fixing...

Question 7

Flat mild steel bearing plates are used
A)For points and crossings in the lead portion
B)With wooden sleepers at locations where creep is likely to be developed
C)On all joints and curves
D)On all the above

Accepted Answer

The answer of Flat mild steel bearing plates are used
A)For...

Question 8

Composite sleeper index is the index of
A)Hardness and strength
B)Strength and toughness
C)Toughness and wear resistance
D)Wear resistance and hardness

Accepted Answer

Composite sleeper index is the index of hardness and strength.

Question 9

Staggered joints are generally provided
A)On curves
B)On straight track
C)When two different rail sections are required to be joined
D)None of the above

Accepted Answer

Staggered joints are generally provided on curves to reduce the impact of wheel loads on the track and to improve the stability of the track.

Question 10

Creep is the
A)Longitudinal movement of rail
B)Lateral movement of rail
C)Vertical movement of rail
D)Difference in level of two rails

Accepted Answer

Creep refers to the longitudinal movement of rail, which occurs due to various factors such as temperature changes, braking forces, and vibration.

Question 11

Due to battering action of wheels over the end of the rails, the rails get bent down and are deflected at ends. These rails are called
A)Roaring rails
B)Hogged rails
C)Corrugated rails
D)Buckled rails

Accepted Answer

Hogged rails are those that get bent down and deflected at the ends due to the battering action of wheels, resembling a hog's back.

Question 12

The main function of a fish plate is
A)To join the two rails together
B)To join rails with the sleeper
C)To allow rail to expand and contract freely
D)None of the above

Accepted Answer

Fish plates are used to join two rails together end to end, providing continuity and smoothness to the track.

Question 13

The purpose of providing fillet in a rail section is to
A)Increase the lateral strength
B)Increase the vertical stiffness
C)Avoid the stress concentration
D)Reduce the wear

Accepted Answer

Fillet in a rail section is provided to avoid stress concentration, which can lead to material failure. The smooth transition it creates between two surfaces reduces the sharp corners that can concentrate stress.

Question 14

Two important constituents in the composition of steel used for rail are
A)Carbon and silicon
B)Manganese and phosphorous
C)Carbon and manganese
D)Carbon and sulphur

Accepted Answer

Carbon and manganese are crucial in the composition of steel used for rails. Carbon is essential for its hardness and strength, while manganese improves the steel's durability and wear resistance, which are vital properties for materials used in rail tracks.

Question 15

Flange-way clearance is the distance
A)Between the adjoining faces of the running rail and the check rail near the crossing
B)Between the gauge faces of the stock rail and the tongue rail
C)Through which the tongue rail moves laterally at the toe of the switch
D)None of the above

Accepted Answer

Flange-way clearance refers to the space between the adjoining faces of the running rail and the check rail near the crossing, allowing the wheel flanges of railway vehicles to pass without interference.

Question 16

Which of the following types of sleepers is preferred on joints?
A)CST-9 sleeper
B)Steel trough sleeper
C)Wooden sleeper
D)Concrete sleeper

Accepted Answer

Wooden sleepers are preferred on joints due to their flexibility and ability to absorb shocks, which helps in reducing the impact on the joints.

Question 17

Total effective bearing area of both the bowls of a pot sleeper, is
A)Slightly more than that of a wooden sleeper
B)Slightly less than that of a wooden sleeper
C)Equal to that of a wooden sleeper
D)None of these

Accepted Answer

The answer of Total effective bearing area of both the...

Question 18

Pick up the incorrect statement from the following:
A)Sleepers hold the rails at proper gauge on straights
B)Sleepers provide stability to the permanent way
C)Sleepers act as an elastic cushion between rails and ballast
D)None of these

Accepted Answer

All the statements provided are correct regarding the functions of sleepers in railway tracks. Sleepers do hold the rails at the proper gauge, provide stability to the permanent way, and act as an elastic cushion between the rails and ballast.

Question 19

On Indian Railways, number of a crossing is defined as
A)Sine of angle of crossing
B)Cosine of angle of crossing
C)Tangent of angle of crossing
D)Contingent of angle of crossing

Accepted Answer

The answer of On Indian Railways, number of a crossing...

Question 20
