Please aim to arrive at bus stops 5 minutes before the time shown. Our buses should leave main stops no later than 5 minutes past the scheduled time, and no earlier than 1 minute before. Drivers use main stops to keep running on time, but times for stops in between these are only estimates and drivers are not asked to wait at these stops. We do our best to run our buses on time, but please allow plenty of time to catch the bus and any connections, as not everything is within our control.
