A note about delays...
If a vehicle is delayed due to an unusual event (such as a reroute, incident, or equipment problem), the arrival predictions may remain the same or may even increase for that vehicle. In the event that a vehicle stops transmitting data to our servers, it will not appear on this Web site, even though it is in service.
