For the last few days, i have been observing that whenever i am trying to find out trains between any two stns, sometimes it is showing all normal, and sometimes it is not working properly...for eg:- Today, i had searched for trains between NDLS and ASR. I received two results--1st, all normal, i.e., presence of substantial no of trains; 2nd, no trains between these two stns. Same case occurred with trains between DHN and ASN. Can anyone pls tell what's the problem exactly that this incident is occurring???....pls help if anyone knows the way out of this menace
