For NDLS-Gwalior.. it took them 2 months to revise.. for the Gwalior-Jhansi. it takes 3 more months.. Jhansi-Bhopal 5 months Bhopal-Nagpur (no change probably).. Nagpur-Ballarsha (2 months) Ballarshaw-BZA 2 months.. if all these is done SCR takes immediate decision in BZA-VSKP.. So it takes atleast an year for Railway Board to understand the facts and then realize.. and revise the TT. :)
