thanks for explanation many time even if train continues to run and pass from one point on schedule time it also take the same time given here to reach next intermediate station so that's amazing.
I have a suggestion for every intermediate station we normally do not want to put pics or url but when we try to update train station it opens a box and then again we write something and paste which takes say 1-2 minutes some time so which gives little inaccuracy so we should have something like a button so that once you click on it right away it update the status. and then after we have option already available to put pics and other info.
