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
Explanation:

25 trains
B
27 trains
C
30 trains
D
35 trains
Correct Answer:
B. 27 trains

Q.197
Medium
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

Q.200
Medium
Which of the following is NOT a function of a railway diesel locomotive's fuel injection system?
A
To atomize diesel into fine particles
B
To inject fuel at precise timing
C
To regulate engine temperature
