@austin eastbound, from Mariner to Pioneer Sq. it says "South." From International District to Mercer Island it says "East." And from South Bellevue to Woodinville it says "North."
And basically the same thing in reverse.

@austin Though importantly, for someone who doesn't know the typical usage patterns of line 2 in Seattle, I could be off. If people taking the 2 starting from Redmond are primarily going past South Bellevue, then it should say "West" instead of "South."
A transit agency that's aware of its riders typical commuting patterns will be able to identify which cardinal directions to list better than I can.
@zed I think you used some future plan map, it's nowhere like the current service. For the part across the lake and in the Eastside (that's how those suburbs are called) an east-west direction makes sense. The problem is the interlining north of the city, how would you distinguish between the two lines in the northern suburbs that both goes south but forks after the city, yet "points east" isn't exactly accurate?
@austin each line gets its own wayfinding.
It’s not like when you’re at the station that shares a line right now it only gives the last station name of line 1 and not line 2. It gives it for both.
So it could say:
Line 1: South (last station name here).
Line 2: East (last station name here).
Again, where it stops saying South and starts saying East will be determined by the by the ridership data on what the most common destinations are for a particular line from a particular station.
