NCERT (2026-27): “On the basis of the width of track of the Indian Railways, three categories have been made: Broad gauge: The distance between rails in broad gauge is 1.676 metre. The total length of broad gauge lines was 63950 km (2019-20). Metre gauge: The distance between rails is one metre. Its total length was 2402 km (2019-20). Narrow gauge: The distance between the rails in this case is 0.762 metre or 0.610 metre. The total length of narrow guage was 1604 km (2019-20). It is generally confined to hilly areas.” |
