GD WDM-3A hauled 21 coach load 15051 Kolkata - Gorakhpur Express accelerates through thick fog and speeds through Bhaironganj Station on Narkatiaganj - Bagaha Section of East Central Railway's Samastipur Division.The fog was very thick as it was quite surprising to see the LP's notching up to decent speed.Enjoy the honking heard in the distance some 13 coaches away from my coach and of course the track sounds as the train speeds through Bhaironganj.
