What Is a Tripper Bus?

 

Have you ever been passed by a "Not in Service" bus that wasn't completely full?

 

If so, then this bus stop was already served by a tripper bus.  Tripper buses typically start picking up passengers at the scheduled time for inbound stops. Once the tripper starts, the regularly scheduled bus goes "Not in Service" and only drops off its current passengers.  All stops are served only once and more closely to the printed schedule time than would occur if only one bus was operating on the route.

 

Tripper buses are regularly assigned on the A, G, J, W, and Z lines.  It is best to rely on the printed schedule to avoid missing the bus, as bus tracking mobile applications may be less accurate due to two buses operating at once.  We recommend that customers remain aware of the scheduled time when arriving at a bus stop and get to your stop 2-5 minutes BEFORE the scheduled arrival. If you see two arrival predictions that are close together, use the schedule time or the earlier prediction to plan your arrival time at the stop.
