Check out these tips and tricks from Pittsburgh Regional Transit about using public transportation in Pittsburgh, PA.
Pittsburgh Regional Transit (PRT) is the public transit agency for the greater Pittsburgh area, providing bus, light rail, incline and paratransit service to about 230,000 riders daily.
For bus service and the "T" - Pittsburgh's light rail system - pay as you enter at the front door. This policy is in effect at all times.
You can transfer between the 28X (from the Pittsburgh International Airport) and most other PRT bus or "T" routes in downtown Pittsburgh. PRT fare is $2.75 for unlimited rides within a three hour period. Riders can purchase fares at the ticket vending machine near Door #6 next to baggage claim. Exact change is required when paying with cash as bus drivers do not carry change. Travel between the Downtown and North Shore is free on the light rail system.
