Well some more information, as i was thinking these kinda query later on!!
Mr. Manish has given wise statement, about the same!!
#
Now, watching empty berth, doesnt mean, the train is empty!!
Have a...
more... look, HWH to Champa falls under GNWL & so if berth are empty from HWH, but same would be booked from KGP/TATA/CKP/ROU/JSG/RIG/CPH, under the same GEN Quota, which are been shared by all these stations.
Now, if search for booking from HWH-Champa or any station between them, status will be different & quite vacancy is visible!!
#
The berth which are looking vacant, actually arnt that vacant, as the Quota is full & under waiting and its no game by IR.
#
Even, if HWH-Champa stretch is empty, it will not clear WL for HWH-PUNE or any GNWL!!
#
Being departing late & in morning hours, many travellers doesnt prefer this train (as many got overnight travelling option earlier, for HWH-Champa stretch) & that may have been the reason for non/less utilization of Quota between HWH-Champa!!
