Unfortunately the official website does not show this information as to which are berths are used to display availability. Also in case of RLWL, it does not show which station's quota is used and WL maintained. e.g. this train has RL quotas defined at Pune, SUR, GR, Wadi. Each station will maintain its own RLWL, but looking at website we wont be able to differentiate which RLWL are they talking of.
