Improving the Line 89 schedule

showing that it actually operates as a loop


TriMet Line 89 used to run between Sunset TC and Tanasbourne along Cornell and Bronson Roads and 185th Avenue. As seen on the map, the western portion of Line 89 was split into two halves, a northern "via Bronson" one and a southern "via Cornell" one. Buses alternated between the two, and the line operated hourly on the weekends.

The real problem with Line 89

It was not evident that the buses actually switched between the Bronson and Cornell halves at the western end of the route and continued on the other one back to Sunset TC. Moreover, given the low frequency on the route, this was very useful--many times taking a bus that's currently headed towards Tanasbourne (the opposite direction) would get you towards Sunset TC earlier. On weekends, as the highlighted column in the image above shows, buses only traveled each direction of each half (e.g. east on Cornell) every two hours.

In addition, making this clear would have also helped people trying to get between the two halves of the route.


Instead of dividing each direction into two halves, describe the route as a loop, with buses alternating directions around it:

I don't think the "89 Sunset TC" is correct, but note the "which continues as"

Line 89 schedule vs. the trip planner

The "To Sunset" schedule (top) sounds like all trips start at the same stop, when half of them actually start at the stop across the street. The trip planner (bottom) correctly shows that only the "B" trips actually stop there--that there really is no 6:31am, 8:31am, 10:31am, etc Line 89 buses at Stop ID 10039.
