Yes, as Mr. Murli said, we already have a train search + date + quota feature, which will return availability info for all trains in one shot. However, Mr. Jitesh is also right in that the info is not fresh on a minute-to-minute basis. If the availability has already been retrieved, then we don't get it again, so as to not load the official servers too much.
In light of your request, we can make changes so that if the availability is already RAC or waitlist, we don't refresh it, since only the WL/RAC numbers will go up. But, if the status is currently showing "Available", we always show up-to-the-minute info, because it can change to RAC/WL at any time.
@all:...
more... Please remark on the above. Thanks.
