Previously I was thinking that the main cause of slow speed of 07643 is the single diesel line between Vijayawada and Nidadavolu.
Now Vijayawada-Bhimavaram Town is doubled and electrified but the speed has not been increased.
The...
more... main reason seems to be extremely heavy traffic between Nidadavolu and Samalkot. We desperately need a third line there if we are to increase 07643 speed. 07643 runs well till Nidadavolu but gets caught for freight/superfast train overtake. Nowadays it is arriving 45-60 minutes early to COA.
Railway Budget approved third line between Vijayawada-Duvvada. Could anyone kindly update status of that project?
