Thanks.
Then would it be better to change the trains at KGP with same train chain?

Any suggestions?

I would say it would hardly make any difference... Its hard to believe that 12864 would be overtaking 12801. So if you can catch this at KGP you could very well catch from BBS. And suppose if you miss at BBS you are not gonna get it at KGP also.. To me this looks a little too tight

Thanks.
I thought KGP, instead of BBS would be better for change-over, when i saw lot of slack time for 12864 between BBS and KGP and also, 12801 halts @ KGP for good 25 minutes for loco reversal.
So, even if 12801 reaches KGP first and 12864 reaches 20 minutes later, still we can make it. I had taken that risk and booked a ticket for KGP-BKSC journey for my colleague and have to book a CK ticket in 12864 tomorrow.

you may catch it at kur, a station before bbs. generally 12864 and 12801 meet each other at kur. but if u miss it there, then u can only catch it at kgp.
