I was traveling in this train from BSP to Panvel today. It arrived 30 mins (approx) late at BSP and continued getting late till NGP where it reached 1.5 hrs late. After NGP, it had a good run till IGP (Igatpuri) where it reached at 11:00 PM (approx 2 hrs late ) which is normal as it was 1.5 hrs late at NGP only. To my surprise and I don't know the reason why, it was controlled for 3.5 hrs between Igatpuri and Kasara. It was halted for 1 hr at Igatpuri and 1.5 hrs at Kasara and reached Kalyan at 3:20 AM. Though it had yellow signal in Kalyan (as its not a commercial/technical stop for this train) but the train halted for a minute at Kalyan.
