Tough to increase the speed. Most of the times, this train runs in mileage mode from VSKP to HWH.
The 1st gear is put, accelerator is pressed, the train picks up some speed and gear is shifted to neutral and train reaches next station. So, where is the chance to increase speed? It halts for every 30-40 mins of run for 2-3 hrs.
And it gets the best avg in single line, diesel powered and terrain region of SC GNT.
