Deccan Queen - मेरे सपनों की रानी

When the quota of these intermediate station gets exhausted and directly moves to GNWL, one needs to be careful while purchasing these tickets. If I book a waitlisted ticket from HWH-R, some other passenger might or might not book for R-CSTM or any other station enroute. In such cases, the system would prefer to allocate any vacant berth who would travel all the way through.
For example: HWH-R=> WL 1
HWH-CSTM => WL 2

is no waitlisted passenger for R-CSTM. Thus WL 2 would be confirmed and WL 1 would not. This is precisely why you would find passengers often complaining that a person having waitlisted status more than me got confirmed.
Alternate:-
HWH-CSTM=> WL 1
HWH-R=> WL 2
R-CSTM=> WL 3
1. Now if a confirmed passenger for HWH-R cancels the ticket then WL 2 would get preference. In such cases WL 1 and WL 3 would remain as it is.
2. If case 1 happens, plus if a confirmed passenger from R-CSTM cancels his ticket, both WL 2 and WL 3 now gets confirmed. WL 1 remains as it is.
