Q8 | Which of the following statement is correct?

The tongue rail should be longer than the stock rail.

The tongue rail should be smaller than rigid wheel base of the vehicle.

Track spacing is the distance between the running edge of stock and switch rails at the switch heel

Facing points are such places in the track where trains first pass over switches and then over crossings.

double sleeper

none of these

Q15 | The speed of the locomotives will be more if the gauge is wider.

Correct

Incorrect

Q16 | The type of sleeper used, depends upon

initial and maintenance cost

easy fixing and removal of rails

provision for sufficient bearing area for rail

all of the above

wooden sleepers

concrete sleepers

steel sleepers

CST - 9 sleepers

Q19 | The fish plates should be designed for

bearing the vertical and lateral stresses

allowing free contraction and expansion of rails

easy renewal and replacement of rails

all of the above
