First of all, what I have seen is, the passengers in this train are majorly (around 60-65%) the ones residing in Magadi Road areas, Tumkur Road areas, Devanahalli Road areas, Krishnarajapuram side areas.
Calculate the time taken from Yelahanka to their areas and from Yeshwanthpur to their areas..
From the beginning, people of Devanahalli Road and Krishnarajapuram areas deboard at Yelahanka.
Two...
more... options for people of Tumkur Road areas and Magadi Road areas..
Either YPR or YNK
Consider Jalahalli Cross (If u don't know search in google maps)
Only travelling time considered
YNK to Jalahalli cross - 30 mins (Avg) in all means of transport
YPR to Jalahalli Cross - 25 mins (Avg) in all means of transport
But in the case of YPR you have to travel 20 mins more making up travel time 45 mins..
So obviously the one who knows the city very well would deboard at YNK, both to save money and time..
Also you get frequent buses to Kengeri side via Tumkur Road, Magadi Road
