Railway Engineering Set 20 MCQs

Q1 | The fillet in a rail section is provided to

increase the vertical stiffness

increase the lateral strength

reduce wear

avoid stress concentration

Q2 | The spike used for fixing chairs of bull headed rail to wooden sleepers is

dog spike

round spike

elastic spike

all of these

Q3 | The spike commonly used to fix the rails on wooden sleepers is

dog spike

round spike

screw spike

all of these

Q4 | Which of the following statement is wrong?

The fish plates are so designed that they fit the underside of the rail head and top of the rail foot in case of front footed rails.

Now-a-days, fist plates are manufactured of steel.

Due to entering of sand between contact surface of rail and the fish plates, the wearing of fish plates start.

In case of steel sleepers, the chairs are not welded.

Q5 | The length of each fish plate is

317.5 mm

457.2 mm

514.3 mm

623.4 mm

Q6 | The distance between two adjoining axles fixed in a rigid frame is known as

gauge

wheel base distance

creep

none of these

Q7 | The spacing of sleepers is kept

closer near the joints

closer at the middle of rails

same throughout the length of rail

none of these

Q8 | The maximum value of throw of switch for a broad gauge track is

89 mm

95 mm

108 mm

121 mm

Q9 | In the cross - sections of railway tracks, the side slope in cutting is same as that in embankment.

True

False

Q10 | The standard size of timber sleepers in railway tracks of metre gauge and narrow gauge is same.

Yes

No

Q11 | When the train moves on the rail, it causes constant reversal of stresses.

Right

Wrong

Q12 | Creep causes

opening of rail joints

distortion of points and crossings

buckling of track

all of these

Q13 | For metre gauge, 49.8 to 52.3 kg/m rail section is used.

True

False

Q14 | Trailing points are on the

same

opposite

Q15 | The rail section first designed in Indian railways was

double headed type

bull headed type

flat footed type

none of these

Q16 | On Indian railways, cant deficiency allowed on broad gauge track is

56 mm

66 mm

76 mm

87 mm

Q17 | The maximum limit of superelevation prescribed by Indian railways on narrow gauge is same as that on metre gauge.

Agree

Disagree

Q18 | The minimum composite sleeper index for wooden sleepers used over bridge girders, is

1352

1455

1555

1652

Q19 | In India, permissible limit of rail wear is

5%

10%

25%

30%

Q20 | A good sleeper whould be such that

the rails can be easily fixed and taekn out from the sleeper without moving them

it can provide sufficient bearing area for the rail

it can provide sufficient effective bearing area on the balast

all of the above

Q21 | George Stephenson succeeded in running the first train of the world in

1825

1835

1841

1853

Q22 | The maximum limit of superelevation prescribed by Indian railways on broad gauge is

76.2 mm

0.767 m3

1.11 m3

1.51 m3

2.11 m3
