Interesting observations of the chart of train 12618 that left Nizamuddin on 14-Nov-2013 and which eventually met with an accident on 15-Nov:
Coach A1, Berth 20, CK quota berth, defined from NZM to ERS, was given to 5 passengers in different segments:
NZM MRA
GWL BPL
BPL...
more... KYN
KYN CHI
MAJN AWY
Infact check passengers allotted to S1 (all berths defined from NZM to ERS). Almost all berths have 3 or 4 passengers assigned to it.
No wonder why so many WL tickets get confirmed at charting.
