This will tell you which direction the bus is traveling in relation to the timetable below it.
The circles along the route indicate a stop where the bus is scheduled to be at a certain time. The letter in the circle corresponds to the letter on the timetable. Using these together, you can determine how long it takes the bus to travel different sections of the route.
These are noted by symbols next to certain times, like "•" and "*". Please read the notes at the bottom of the timetable which they correspond to, as they contain information that could influence your trip planning.
If you need to reach Customer Service, the phone number and email address is on every schedule.
