Trying to book ticket online for 8th December 2016 for the train 12018 Dehradun Shatabdi with Originating station as Dehradun (DDN) and Destination station as New Delhi (NDLS). However, I am getting result as "ISL STN DELETED" . In an earlier post on this forum it was mentioned that this means that a particular train would henceforth not stop at that station. But DDN is the originating station i.e. this train starts from DDN :) and the train itenary is still showing that it runs on all days, then, why this message is being shown ? Can someone help please ??
