Sir,
Once a while click on 'Auto Update Train Location link' provided in trip diary.[ It will use GPS and your device might ask for switching on GPS if not done (only once) and select yes/Ok]
After clicking the link ... the blog entry box will show the location.... "x kms from....." or " @ Y JN"... Just Click post and...
more... it will be done....and your trip diary will get updated and will show the exact delay....
Regards
