15204 Down Lucknow (LJN)- Barauni (BJU) Express departs Gorakhpur Junction with GD WDM-3A giving some nice chugging action.Notice the non burnt fuel particles burning out at the end of the exhaust..it looks just awesome in the darkness of the night.The tail end of Manduadih(MUV) - Lucknow(LJN) Krishak Express can also be seen as it was waiting at the outer signal for clearance.
