Twin WDG-4 Acceleration Indian Railways. MUed WDG-4s from DLTB shed hauling 14727 Shriganganagar - Tilakbridge Passenger (Express fare). The train accelerates out of Gurgaon at a sedate pace, however, beyond 30 KMPH is still worth the watch. Also, notice the smoking after 60 KMPH. Don't miss out Shahabad Mohammadpur departure from outside (It felt better than Gurgaon departure)
