#BookingTip.
If wish to travel from Tatanagar to Delhi , and getting heavy waiting list or regret in this train for SL class, then Book Kharagpur to New delhi and change boarding point to Tatanagar.
Tata is in RLWL quota whereas KGP is in GNWL quota, thus having more chance of confirmation or atleast getting RAC if take GNWL below 60-70 in Sleeper class.
Just...
more... Rs 40 excess fare is spent but confirm ticket can be get.
