I am going to book tickets in 17604 from YPR to KCG for tomorrow's journey (10-3-17) once i reach home from office. As of now the GNWL is 25... i heard that this train has good clearance.. till what WL number i can book in GNWL rather than booking in TQ... experts pls throw some light on it... i dont want to waste 100 bucks, since ppl may suggest some good predictions.. :P
