I have been travelling on almost all shatabdis between Delhi and Ambala since i work in Gurgaon and my home town is at Ynr. I make 8 - 10 trips every month. Seriously have not seen any enthusiasm from pax from PNP to board this train in both ways since past 7 years !! there can be many reasons primary being its proximity to Delhi less than 90 Kms ; good road infrastructure ; high ratios of labor class ( business classes don't take trains for 85 kms of journey) and good bus services readily available at any time of the day !!!
I generally stand at the door when shatabdi halts at such stations to roughly estimate the pax boarding...
more... / de boarding the train. The max from PNP in any direction i found was under 5 :P it is seriously a waste stop !!
