We know that looking for your line, while on the street can be a stressful task, when you’re not sure which direction you’re supposed to be going.
That’s why we’ve added arrows to every route map - so now you can know where your line is heading, and even which side of the road you’re meant to be on.
Where Can I See This?
Whenever you view a Line Details screen either by choosing it from a Station screen or the Lines list, you can tap on the Map View icon (or swipe down) and see the route and direction marked on the map.
Another option to see these directions is if you’re planning a trip: just choose one of the Suggested Routes to view the Directions screen and the route on the map will include a direction arrow.
