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?
Answer: A
Speed of first train = 9540 = 60 km/h; Speed of second train = 6540 = 90 km/h; Difference = 90 - 60 = 30 km/h
Q.382Medium
What is the primary purpose of a pantograph in electric trains?
Answer: B
A pantograph is an apparatus that maintains contact with overhead electrical lines to collect power for electric trains.
Q.383Medium
What is the standard height of platforms at railway stations in India?
Answer: B
Standard platform height in Indian Railways is 0.75 meters (2.5 feet) for broad gauge to ensure safe passenger boarding.
Q.384Easy
Which of the following is a characteristic of an express train compared to a local train?
Answer: B
Express trains have fewer intermediate stops, allowing them to maintain higher average speeds compared to local trains.
Q.385Easy
In railway signaling, what does a red signal indicate?
Answer: B
A red signal in railway signaling is a mandatory stop signal indicating that trains must not proceed beyond that point.

Q.386Medium
What is the function of a turntable in a railway depot?
Answer: B
A turntable is a rotating platform used in railway depots to turn locomotives around and position them for maintenance and service.
Q.387Medium
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?
Answer: B
If freight:passenger = 3:5 and passenger trains = 45, then freight trains = (53) × 45 = 27 trains
Q.388Easy
What is the gauge of the Indian railway network that covers the majority of the system?
Answer: A
Indian railways predominantly use broad gauge (1676 mm) which covers approximately 43,000 km of the total network.
Q.389Easy
Which of the following is the primary function of a buffer in railway couplings?
Answer: B
Buffers are spring-loaded devices that absorb shocks and minimize damage during coupling and uncoupling of railway carriages.
Q.390Medium
What is the minimum braking distance required for a train traveling at 100 km/h according to Indian Railways standards?
Answer: C
Indian Railways specify a minimum braking distance of approximately 500 meters for trains traveling at 100 km/h under normal conditions.
Q.391Easy
In railway terminology, what does 'rake' refer to?
Answer: B
A 'rake' is a complete formation of railway coaches or wagons that are coupled together to form a train unit.
Q.392Medium
What is the primary advantage of AC (alternating current) traction over DC (direct current) in electric trains?
Answer: B
AC traction systems are more efficient and require lighter overhead equipment compared to DC systems, making them economical for long-distance routes.
Q.393Easy
Which component in a diesel locomotive is responsible for converting chemical energy into mechanical energy?
Answer: C
The diesel engine is the primary component that converts the chemical energy stored in diesel fuel into mechanical energy through combustion.
Q.394Easy
What is the role of 'ballast' in railway track construction?
Answer: B
Ballast, typically made of crushed stone or gravel, supports the sleepers and distributes the train's weight evenly to the subgrade.
Q.395Medium
In the 2024 Indian Railways modernization, what is the primary objective of the 'Gati Shakti' program?
Answer: B
Gati Shakti is a national master plan to develop integrated multimodal infrastructure for economic growth and faster movement of goods and passengers.
Q.396Medium
What is the standard distance between two consecutive railway stations classified as 'block sections'?
Answer: B
Block sections in Indian Railways typically range from 5-10 km, which is the distance between consecutive signal posts for safety purposes.
Q.397Medium
Which of the following is NOT a function of a railway diesel locomotive's fuel injection system?
Answer: C
Regulating engine temperature is the function of the cooling system, not the fuel injection system. The fuel injection system focuses on fuel atomization and precise timing.
Q.398Hard
What is the maximum permissible speed for a train on a sharp curve with a radius of 400 meters in Indian Railways?
Answer: B
For a curve radius of 400 meters, the maximum safe speed is approximately 60 km/h to prevent derailment due to centrifugal forces.
Q.399Easy
In railway signaling systems, what does a 'yellow signal' indicate?
Answer: B
A yellow signal indicates 'caution' - the driver should prepare to stop at the next signal as it may show 'stop' indication.
Q.400Medium
What is the primary purpose of a 'screw coupling' in older Indian railway coaches?
Answer: B
Screw couplings were used in older Indian railways to manually connect coaches together, though they have been largely replaced by automatic couplers.
