As per TT 12273 MGS Mughal Sarai Junction» X T¶ 20:50 - 21:00.
I had seen it arrived at 8.48 PM yesterday so it was not delayed.
Yes it has got ALD departure at 10.45 PM.
Since 12273 has no slack between any stations (unlike 12393 which has 1 hour slack between ALD-CNB (3 hours while 130 MPS cover it in 2) and another 1 hour between CNB-NLDS (6 hours...
more... while similar MPS cover it in 5)
