1. The gauge of railway track is defined as
- the distance between the centres of the rails
- the distance between the inner faces of the rail heads
- the distance between the outer faces of the rail heads
- the distance between the webs
2. The standard gauge width for broad gauge is
- 1.2 m
- 1.767 m
- 1.752 m
- 1.676 m
- 1.525 m
3. Narrow gauge is adopted where?
- Terrain is hilly
- Number of river crossing are more
- Expected revenue earning is low
- Acquisition of land is difficult
4. The railway station at which a track line meets a main line is called
- Junction station
- Way side station
- Flag station
- Terminal station
5. In an electric railway line, the height of catenary contact above the rail top is
- 4.35 m
- 6.78 m
- 3.12 m
- 5.70 m
6. Gauge of a railway track is the measure of
- distance between centre to centre of rails
- distance between inner faces of rails
- distance between outer faces of rails
- distance between the webs of two rails
7. Equilibrium cant for a 3° curve on a Broad Gauge track, if the permitted speed is 70 kmph. is
- 18.85 cm
- 16.20 cm
- 15.85 cm
- 11.25 cm
8. What is the steepest gradient permissible on a 2° curve for a broad gauge line having ruling gradient of 1 in 200?
- 1 in 250
- 1 in 238
- 1 in 212
- 1 in 194
9. For undeveloped areas, the type of gauge adopted is
- Metre gauge
- Broad gauge
- Narrow gauge
- All of these
10. The maximum degree of curvature for Meter Gauge track is limited to
- 16°
- 10°
- 40°
- 30°
- 50°
11. The desirable rate of change of cant deficiency in case of Meter Gauge track is
- 20 mm/sec
- 35 mm/sec
- 55 mm/sec
- 65 mm/sec
- 75 mm/sec
12. The permissible cant deficiency for speed of upto 100 kmph on a Narrow Gauge track is
- 3.8 mm
- 3.8 cm
- 5.1 mm
- 5.1 cm
13. Selection of gauge depends on
- Type of sleeper and ballast
- Points and crossing
- Traffic volume and speed
- Rail strength and rainfall
14. Gauge of a permanent way is
- minimum distance between running face of rails
- width of formation
- distance between centre of rails
- distance between outer faces of rails
15. The grade compensation on 4° curve on a Broad gauge railway track is
- 0.16%
- 0.20%
- 0.08%
- 0.12%
16. The steepest gradient permissible on a 2.5° curve for B.G. line having ruling gradient of 1 in 200 is
- 1 in 235
- 1 in 220
- 1 in 275
- 1 in 250
17. Choice of gauge depends on
- volume of traffic only
- speed of traffic only
- neither (volume of traffic) nor (speed of train)
- both (volume of traffic) and (speed of train)
18. More ‘gauge width’ is recommended
- to attain greater speed
- in hily areas
- for cheap plate laying
- when the trafic flow is highly fluctuating

- 41 mm
- 38 mm
- 35 mm
