Shuttle buses will replace all SEPTA Regional Rail Airport line trains between 30th Street Station  and Philadelphia International Airport every weekend this month starting Saturday, the transit agency said.

The changes are due to a track improvement project.

Customers traveling to Center City from the airport should board SEPTA buses in the limo/taxi lanes at Zone 8 at the terminals. Customers traveling through to Glenside and Warminster stations should transfer to trains at 30th Street Station. Passengers traveling to Center City from Eastwick Station will board shuttle buses on Bartram Avenue at the station's driveway.

Passengers traveling to the airport should expect to board shuttle buses at 30th Street Station, where signs will be posted directing them to departure areas.

SEPTA Key Quick Trips purchased at an airport terminal prior to boarding, as well as Mozio
mobile tickets will be accepted for travel from the airport on the shuttle buses.
