Thanks for the info and links.
I have read the F.A.Q.s and have already done some search on Indian railways' websites, but i did not come around anything properly stating whether the luggage could be left at a cloak room which is SITUATED AT a station OTHER THAN originating or destination stations in the journey ticket. IRCM (commercial manual) also doesn't state it properly.
I hope that it is allowed. As it may save time and unessential travel for luggage maintenance. Thanks again.
