The 'gauge' of a railway track in India (broad gauge) is:
Choose the correct answer
1000 mm (metre gauge)
1676 mm (5 ft 6 in) broad gauge — widest standard gauge used in India for main-line railways
1435 mm (standard gauge)
2000 mm (double wide)
Correct Answer
B. 1676 mm (5 ft 6 in) broad gauge — widest standard gauge used in India for main-line railways
Why is this the answer?
Railway gauge: distance between inner faces of rail heads. Broad gauge (BG) = 1676 mm (5 ft 6 in) — used in India, Pakistan, Sri Lanka, Bangladesh. Standard gauge (SG) = 1435 mm — Europe, US, China. Metre gauge (MG) = 1000 mm — now being converted to BG. Narrow gauge (NG) = 762 mm — hill railways. BG allows higher speeds (up to 160–200 km/h), heavier axle loads. RDSO standards cover all BG track design.
