Finally making an appearance, Itarsi WAP-7 #37228 powering 15159 Chhapra⇌Durg Sarnath Express enters into Durg Junction like a snail. Itarsi WAP-7 is supposed to be Sarnath's Proper Link, however, I have rarely spotted an Itarsi P7 serving with Sarnath, all thanks to the equally proper link mismanagement in Indian Railways!
