Railway recruitment covers several exams with overlapping syllabi, so one round of preparation serves RRB NTPC, Group D, ALP, Junior Engineer and Technician. Questions here cover mathematics, general intelligence and reasoning, general science, and general awareness including current affairs. The science section is pitched at the level the RRB papers use, which is closer to school syllabus than to competitive exam theory.
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.42Medium
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.43Medium
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.44Medium
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.
Q.45Medium
What is the thickness of a standard Indian railway sleeper (tie)?
Answer: B
Standard Indian railway concrete sleepers are typically 200-250 mm thick to provide adequate support and distribution of train loads.
Q.46Medium
What does the term 'cant' or 'superelevation' mean in railway engineering?
Answer: B
Cant or superelevation is the banking of the outer rail on curves to counteract centrifugal force and allow trains to maintain higher speeds safely.
Q.47Medium
What is the main advantage of using 'welded rails' in modern Indian Railways compared to 'jointed rails'?
Answer: B
Welded rails eliminate expansion joints, resulting in reduced noise, vibration, smoother passenger ride, and improved fuel efficiency of trains.
Q.48Medium
What is the purpose of 'ballast' in railway track construction?
Answer: B
Ballast (crushed stone/gravel) distributes the load from sleepers and rails, provides proper drainage, and maintains correct track alignment and gauge.
Q.49Medium
Which Indian Railway zone has the longest route length as of 2024?
Answer: A
Central Railway operates one of the longest route networks among Indian Railway zones, covering major parts of Central India.
Q.50Medium
In automatic train protection systems, what does an 'aspect' in railway signaling indicate?
Answer: B
Signal aspects (green, yellow, red) communicate specific instructions to train drivers regarding speed and movement permissions at that location.
Q.51Medium
What is the primary reason for providing 'expansion joints' in railway tracks?
Answer: B
Expansion joints accommodate the linear expansion of rails in hot weather and contraction in cold weather, preventing rail buckling or breaking.
