Very disappointed controlling by CR yesterday. This train was late by 30 mins at Puntamba, reached at 7:20 pm. Since SNSI VSKP exp was about to depart from SNSI at 7:35 pm they did not allow this to SNSI. Even VSKP exp reached PB at 8 pm, still they did not allow it to depart instead they made SNSI DR exp to depart at 8:10 pm and waited till 8:40 pm for its arrival at PB. Finally they departed this at 8:40 pm and train reached at 9:05 pm, almost 2 hrs late. If they did not halt this at PB, it would have reached at 7:45 pm and VsKP exp could have departed just 10 mins late which it would have anyway covered till MMR. There are 3 platforms at SNSI. Given this situation, very disappointed controlling.
