There were departures from Portland every 20 minutes from 6:00 AM to 7:00 PM, at which point it dropped to every 30 minutes until midnight. Leaving Vancouver, on the other hand, required a bit more planning—departures were every 40 minutes from 6:45 AM to 11:15 PM. Seven days a week, though on Sunday mornings they didn’t start until 7:40 AM.
