SEPTA will start selling one-day Regional Rail passes for the papal visit Monday at $10 each, with sales limited to 10 per purchase and available only online.

SEPTA officials said 175,000 passes will be sold for each day of the visit by Pope Francis, Sept. 26 and 27.

For non-rail passengers, three-day papal passes for subways, trolleys, and buses will go on sale online on July 27. SEPTA will sell 750,000 of those passes, good for Sept. 26 through 28.

On subways, trolleys, and buses, customers can also use tokens, and regular weekly and monthly passes.

All passes will be available through SEPTA's website, Passes will be mailed to purchasers, with a $1.95 shipping fee per purchase.

Regional Rail passengers will not be allowed on trains without the passes, and trains will stop at only 21 stations. The Center City stops will be 30th Street Station, Jefferson Station, and University City Station.

Parking will be virtually nonexistent, so SEPTA officials urged visitors to get dropped off at the outlying stations for the trip into Center City.

Passes must be purchased for a specific station and time period. Two morning time periods will be available: 5:30 to 8:30 a.m., and 8:30 a.m. to noon each day.

Return trips will operate from 5:30 p.m. to midnight each day.
