Dear Murli Ji
The site was showing availability earlier also but I checked many times it sometimes does not match with official website and this problem is right now there, before writing these words I cross checked for a train
so for availability we can trust this information
so the point is why not to validate it and make it trustful for regular users...
more... so that this site can attract more users
but
Dear Mr Moderator
