For some bloggers, this this is how the ticket will get confirmed. 2627 has 3 AC3T coaches. Bhopal to New Delhi tickets are given from BSL RL quota (I guess so, it may be other but does not change the analysis). Now this train has many passengers from Bangalore to Itarsi or Bhopal who are booked in the GN quota. Also some Solapur/GR to Bhopal or Itarsi who are booked in Solapur/GR RL quota. Now when the charting for Bangalore, GR, SUR quotas is done, the system detects that all these berths are unoccupied beyond Itarsi / Bhopal. It also sees that in other quotas, there are WL passengers, who can actually be "fitted" in those vacant slots. Hence the system confirms all such WL passengers during charting. These passengers do not have to wait for any cancellations in their own quota to get their booking confirmed.
