The three slip coaches (one Ac2, two sleeper) are attached for Hubli in Kacheguda - Yashwantpur express but when checking the availability of births for Hubli in www.indianrail/gov/in web site, it is not showing any status even though train is being shown. Same is the case while booking online reservation from irctc web site but if you go to the counter and book reservation, you get it without any problem. Can anybody let me know as why is this and what is the solution?
