Tatkal in this train is again cumbersome, as it starts a day earlier to ur journey date!!
U have to make reservation with boarding station not LKO, but the one falling on first day loop!!
Then u have to change boarding b4 24 hrs sch dep, from booked station!!!
I advice u to book in another option, nearby ur journey plan, which can act...
more... as back-up, in case u didnt get conirmed in this train!
