Sir,
Put KDGH in the 'From Station' or 'To Station' fields on the left top corner and after pressing search, you will find the train which stop at Kodigehalli.
Put YNK in the 'from station' and SBC in the 'to station' fields and you will get all those trains which stop at this station or pass through running between Yenhalanka & Bangalore.
Likewise,...
more... in stead of YNK, a bigger junction can be put in to where some train/s go/es via Kodigehalli.
Whatever trains you get this way, the return trains can normally be ascertained by adding 1 to the number when the earlier number is odd or subtracting 1 from the earlier number when the same is even.
(Suggestions from other bloggers / Admins will be helpful to me too.)
Thanks!
