Worksheet time: 8mins
In a turnout, the term facing direction refers to the case where the train:
Enters the crossing first and then the points
Enters the points first and then the crossing
Passes only through the branch line
Reaches the nose of crossing before switch
The tongue rail of a turnout is best described as:
A fixed rail forming the main track
A movable tapered rail working against stock rail
A rail provided only at crossings
A check rail preventing derailment
Head clearance (or divergence) of a turnout is measured at the:
Toe of switch between tongue and stock rail
Heel of switch between tongue rail and stock rail
Nose of crossing between point and splice rail
Flare region of wing rail
Throw of switch is defined as the distance between:
Gauge faces of both stock rails
Running face of stock rail and tongue rail at heel
Running face of stock rail and toe of tongue rail
Two wing rails at the crossing
Which rail guides the wheel flange safely through a crossing and prevents side-ways movement?
Point rail
Wing rail
Splice rail
Check rail
In Indian Railways practice, the turnout angle is commonly specified by:
Cosine of crossing angle
Tangent of angle
Cotangent of angle
Secant of angle
A turnout constructed without any right-angle crossings is characteristic of:
Square crossing
Diamond crossing
Scissors crossing
Gauntlet track
Assertion (A): Check rails are provided near crossings to prevent derailment. Reason (R): They restrain excessive lateral movement of wheels by controlling flange way clearance.
Both A and R are true and R explains A
Both A and R are true but R does not explain A
A is true but R is false
A is false but R is true
A turnout is a combination of __________ and __________.
(a)
The ending point of a tongue rail is known as the (a) of the switch.
The rail of the main track forming one side of a crossing is called the (a) rail.
The rail of the branch track meeting the point rail at the nose is called the (a) rail.
The rail which continues from the heel of tongue rail to the nose of crossing is known as the (a) rail.
Gradual widening of the distance between wing rail and check rail is termed as (a) .
In a gauntlet track, two tracks are narrowed for a short length without using a (a) .
