A suggestion was made to take Line 20 to Line 57 as an alternative for getting to the west side, as both run very late. However, it turns out that Line 20 may just miss Line 57 at night. This means that riders either have to wait a long time at Beaverton TC or that trips are not possible.

It is true that it's virtually impossible to please everybody, and during the day time making one transfer work can break others. But at night and when there's a directional flow of riders, shifting a schedule by just a few minutes can make transit be an option.
