There has been much discussion over the portion of Route 7 to Prentice St. Metro itself has planned on terminating Route 7 at Rainier Beach station, but never got the funding for the trolley wire.
When Metro finally gets the funding for this wire, I think Route 7 should always terminate at Rainier Beach station. I propose a short trolleybus route that runs between RBS and Prentice St to replace the Route 7 tail. This trolleybus could run at 30-minute frequency 7 days a week, possibly using 40-foot buses. The riders of the old Route 7 tail would then have a much faster ride to downtown with a transfer to Link. Late-night and early-morning trips can change to/from Route 7 at RBS for a connection to Atlantic Base.
