As per the map, it seems that my train 12357 Durgiana Exp must have gone from Chitpur Terminal to Dankuni Jn in a very round about way... this section is extremely slow and my train had to stop for 2 times in every 10 mins [Near Patipukur and Dum Dum]... it only speeded up from Rajchandrapur onwards and maintained a rockstar performance up to Mughalsarai on Day 1 ;-)
