Starting Jan. 1, 2011, senior and disabled riders on Sound Transit buses and light rail trains will pay the same $.75 flat fare for in-county bus and light rail trips.

Currently, Regional Reduced Fare Permit holders pay $0.75 for one-zone and $1.25 for two-zone ST Express bus rides, and $0.75 through $1.25 per trip on Link light rail trains. When new fares take effect at the beginning of the year, senior and disabled riders will pay a flat rate of $0.75 for one- and two-zone ST Express bus and all light rail trips.

Sound Transit is changing its regional reduced fares to match King County Metro Transit fare changes that will also take effect Jan. 1.

Fares for Sounder commuter rail and adult, youth and inter-county reduced fare riders on Central Link and ST Express buses will remain unchanged.
