Times are TfL's scheduled first departures from each stop in the given direction; the final stop's time is an arrival. Columns cover the days shown in their heading, and the highlighted column is today. On busy mornings buses can run a few minutes later than scheduled, so allow a small buffer if the first bus matters for a connection.
