Again correct
@MR MODERATOR:
06687 originates from TEN ! 06687 TEN JAMMU EXP 18/04/2010 TIRUNELVELI MON
PLEASE UPDATE !!
I think the confusion is arising from the fact that there IS A TRAIN 06687, AND...
more... THERE IS A TRAIN 6687 WHICH ORIGINATES FROM MDU !!!
DITTO FOR 06317.. The prefix 0 has become significant !!!
If you input 06317/06687, indianrail.gov.in throws up the two trains....
Good wishes.
