Station Code for Gandhidham is wrongly indicated in Trains At A Glance as GIM. If you have used this code to check accommodation availability it reveals that the station is NOT REACHABLE BY THIS TRAIN. But when I used the correct station code GIMB, I could get availability position for different dates. Tickets are waitlisted for 12th and 26th but available for 19th August and other dates. So pls try using GIMB as station code for Gandhidham.
