If you are boarding this train end to end then I will remind you that you are boarding a passenger train between Kolkata to Anand Vihar with top speed 88kmph.Stops on every stations,punctuality is also pathetic.Better to do a break journey instead of boarding this train.It takes 39hrs to cover the journey,and if late then it takes around 50hrs.In 50hrs you will go from koaa to anvt and return from anvt to koaa in any express train.
