GOLDEN QUADRILATERAL

Jan. 10, 2021

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.

About:

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.
This included heavier rails, laying of 260 meters Long welded rail panels, improvement of curves and gradients among others.
Already, the maximum speed limits in the High-Density Network (HDN) between Secunderabad – Kazipet (132 Kms distance) had been enhanced to 130 kmph.
