Current trains me bhi slack boht h
eg- Saraighat Exp actually takes 3h but due to high traffic in night after Barsoi jn
Njp shatabdi - takes 3h 10 min but again traffic slack
So on reality it takes 2.5 hr but only train to cover in this time is 22301 Hwh NJP Vande Bharat Exp. No other train covers in this duration
