Answer & Explanation
Option: Both A & B
Explanation:
Indian Railway has started the New Year by achieving a landmark achievement by drastically enhancing the maximum speed to 130 kmph for 1,280 km length out of 1,612 Km in Golden Quadrilateral - Golden Diagonal (GQ-GD) route. This covers the entire GQ-GD route over South Central Railway, except Vijayawada - Duvvada section, where signalling up-gradation work is in progress. The enhanced speed limits could be achieved due to the systematic and planned strengthening of track & its infrastructure by removing bottlenecks in these sections on a fast pace.
