Waiting for this train on 10-01-2013 to travel from SBC to MAS just after alighting from the staircase in PF 7 where the coach position was indicating C7. The driver promptly stopped it by one coach position ahead, that is C7 stopped where the coach position was indicating C6. All had to run forward to their coaches. There was no clear sign board in C7 coach. An aged couple who have reserved their seats in C6 got into C7 and found them already occupied. Later they realised their mistake and rushed to C6 coach with their baggage. This is also common at BNC for the SBC MAS shadapti
