Each column is one journey, headed by the time it sets off; one that finishes short of the usual end says where ("to …") — not every journey on this route runs the whole way. A · means that journey does not stop there. Times are shown at the route's main timing stops — buses serve all stops in between. Switch a table to All stops for every stop it calls at, or open a stop's own page for live departures there.
