1. What is the primary purpose of railway engineering?
Answer:
Explanation:
Railway engineering involves the planning, design, construction, and maintenance of railway infrastructure, including tracks, stations, and signaling systems, to ensure efficient and safe train operations.
2. What are 'sleepers' in railway tracks?
Answer:
Explanation:
Sleepers, also known as ties, are the rectangular support elements placed beneath the rails in railway tracks. They help maintain track stability and gauge, and distribute the load to the track ballast and subgrade.
3. What is the primary function of a railway ballast?
Answer:
Explanation:
Ballast in railway tracks is a layer of crushed stone or other material that provides support for the sleepers, distributing loads from the rails, facilitating drainage, and helping maintain track alignment.
4. What is a 'railway gauge'?
Answer:
Explanation:
The railway gauge is the spacing of the rails on a railway track. It is measured between the inner faces of the load-bearing rails and determines the size and stability of the railway vehicles.
5. What is the significance of 'super elevation' in railway tracks?
Answer:
Explanation:
Super elevation, or cant, in railway tracks is the practice of raising the outer rail in a curve above the inner rail. This counters the centrifugal force acting on the train, enhancing safety at higher speeds.
6. What are 'points and crossings' in railway engineering?
Answer:
Explanation:
Points and crossings are integral components of railway tracks, allowing trains to move from one track to another. They consist of movable rails, known as points, and fixed crossing pieces that guide the wheels.
7. What is a 'signal' in railway systems?
Answer:
Explanation:
Signals in railway systems are devices that convey information about track conditions, such as clearance, speed limits, and track occupancy, to the train driver, ensuring safe and efficient train operations.
8. What purpose do 'rail joints' serve in railway tracks?
Answer:
Explanation:
Rail joints are gaps or connections between rail sections that allow for thermal expansion and contraction of the rails due to temperature changes, preventing track buckling or breaks.
9. What is 'track stiffness' in railway engineering?
Answer:
Explanation:
Track stiffness refers to the resistance of the railway track to vertical deformation under the load of passing trains. Adequate track stiffness is essential for track stability and durability.
10. What is a 'level crossing' in railway terms?
Answer:
Explanation:
A level crossing, also known as a grade crossing, is an intersection where a railway line crosses a road or path at the same level, as opposed to a railway bridge or tunnel.
11. What is the purpose of 'fishplates' in railway track construction?
Answer:
Explanation:
Fishplates, or joint bars, are metal plates used to connect two lengths of railway track end-to-end, providing a continuous and smooth surface for the train wheels.
12. What is 'track geometry' in railway engineering?
Answer:
Explanation:
Track geometry refers to the alignment, elevation, curvature, and other physical dimensions of the railway track, which are crucial for safe and efficient train operations.
13. What does 'absolute block signaling' mean in railways?
Answer:
Explanation:
Absolute block signaling is a system where a section of track, known as a block, is occupied by only one train at a time to ensure safety. It's a fundamental principle in railway signaling.
14. What is the function of a 'traction substation' in electric railways?
Answer:
Explanation:
A traction substation in electric railways is an installation that converts high-voltage electricity from the power grid to a suitable voltage for supplying to the overhead lines or third rail to power electric trains.
15. What is 'gauge widening' in railway tracks?
Answer:
Explanation:
Gauge widening is the practice of increasing the distance between the two rails on curved sections of the track to compensate for the overhang of the train and to reduce wear on the outer rail and train wheels.
16. What is a 'railway embankment'?
Answer:
Explanation:
A railway embankment is an artificially raised bank of earth or stone, constructed to support the railway track and ensure a level surface where the ground level varies.
17. What are 'cantilever signals' in railway signaling?
Answer:
Explanation:
Cantilever signals are a type of railway signal where the signal head is mounted on an extended beam or structure that overhangs the track, providing clear visibility to train drivers.
18. What is the main purpose of 'interlocking' in railway systems?
Answer:
Explanation:
Interlocking in railway systems is a technique used to prevent conflicting movements of trains through an arrangement of tracks, signals, and switches. It ensures that only safe combinations of these elements can be operated simultaneously.
19. What is 'ballastless track' technology in railways?
Answer:
Explanation:
Ballastless track technology refers to railway track construction that does not use traditional ballast (crushed stone) but instead relies on a solid foundation, like concrete, to support the sleepers and rails. This technology is often used in high-speed rail systems due to its stability and lower maintenance requirements.
20. Why are 'railway turnouts' important?
Answer:
Explanation:
Railway turnouts, also known as switches, are mechanical installations that enable trains to move from one track to another at a junction, providing flexibility and connectivity in rail operations.
21. What is the purpose of 'rail stress' monitoring in railway engineering?
Answer:
Explanation:
Rail stress monitoring involves evaluating the stress and strain in the rails, which is crucial for maintaining the integrity of the railway track, preventing rail failures, and ensuring safe train operations.
22. How does 'track geometry measurement' benefit railway maintenance?
Answer:
Explanation:
Track geometry measurement is a key aspect of railway maintenance, involving the assessment of track alignment, elevation, curvature, and other geometrical parameters. Accurate measurements ensure the track is in good condition, enhancing safety and ride quality.
23. What is a 'rail profile grinder' used for?
Answer:
Explanation:
A rail profile grinder is a machine used to grind the rail head to the desired profile or shape. This maintenance process is important for removing irregularities and ensuring optimal contact between the rail and train wheels.
24. What is the importance of 'railway signaling systems'?
Answer:
Explanation:
Railway signaling systems are crucial for safely managing train movements on the network. They provide signals to train drivers, controlling train speeds, routes, and ensuring safe distances between trains, thus preventing collisions and other accidents.
25. Why are 'anti-collision devices' (ACDs) used in railways?
Answer:
Explanation:
Anti-collision devices are safety systems installed on trains to prevent collisions. They detect other trains on the track, analyze potential collision scenarios, and automatically take control to stop the train if necessary, enhancing safety.
