Looks like the App can track the location very well It seem to be tracking user's location to cancel the train exactly there, where where the users are. I find it much safer and easier to get the right transport at the right time when my location is off. It's a perfect opportunity to meet new people and release stress when I am late. Then I know other people are late too. Thanks!
