What is the primary advantage of AC (alternating current) traction over DC (direct current) in electric trains?
A
Lower initial cost
B
Better efficiency and reduced weight of overhead equipment
C
Easier maintenance
D
Higher safety standards
Correct Answer:
B. Better efficiency and reduced weight of overhead equipment
AC traction systems are more efficient and require lighter overhead equipment compared to DC systems, making them economical for long-distance routes.
What is the minimum braking distance required for a train traveling at 100 km/h according to Indian Railways standards?
A
200 meters
B
300 meters
C
500 meters
D
1000 meters
Correct Answer:
C. 500 meters
Indian Railways specify a minimum braking distance of approximately 500 meters for trains traveling at 100 km/h under normal conditions.
If the ratio of freight trains to passenger trains on a route is 3:5, and there are 45 passenger trains, how many freight trains are there?
A
25 trains
B
27 trains
C
30 trains
D
35 trains
Correct Answer:
B. 27 trains
If freight:passenger = 3:5 and passenger trains = 45, then freight trains = (3/5) × 45 = 27 trains
What is the function of a turntable in a railway depot?
A
To measure train weight
B
To rotate locomotives for servicing and direction change
C
To test brake systems
D
To clean train engines
Correct Answer:
B. To rotate locomotives for servicing and direction change
A turntable is a rotating platform used in railway depots to turn locomotives around and position them for maintenance and service.
What is the standard height of platforms at railway stations in India?
A
0.5 meters
B
0.75 meters
C
1 meter
D
1.25 meters
Correct Answer:
B. 0.75 meters
Standard platform height in Indian Railways is 0.75 meters (2.5 feet) for broad gauge to ensure safe passenger boarding.
What is the primary purpose of a pantograph in electric trains?
A
To provide lighting
B
To collect electricity from overhead wires
C
To control train speed
D
To apply brakes
Correct Answer:
B. To collect electricity from overhead wires
A pantograph is an apparatus that maintains contact with overhead electrical lines to collect power for electric trains.
If a train covers 540 km and takes 9 hours for the journey, and another train covers the same distance in 6 hours, what is the difference in their speeds?
A
30 km/h
B
45 km/h
C
60 km/h
D
90 km/h
Correct Answer:
A. 30 km/h
Speed of first train = 540/9 = 60 km/h; Speed of second train = 540/6 = 90 km/h; Difference = 90 - 60 = 30 km/h
Which device is used to detect broken rails in Indian Railways?
A
Radar detector
B
Ultrasonic testing device
C
Thermal camera
D
Speed gun
Correct Answer:
B. Ultrasonic testing device
Ultrasonic testing devices are used to detect cracks and breaks in rails without damaging them.
What is the composition of steel rails used in Indian Railways?
A
Iron and Carbon only
B
Iron, Carbon, Manganese, and Silicon
C
Aluminum and Steel
D
Copper and Iron alloy
Correct Answer:
B. Iron, Carbon, Manganese, and Silicon
Modern rail steel contains Iron (primary), Carbon (0.6-0.8%), Manganese (0.7-1.0%), and Silicon to provide strength and durability.
