We hope that many of you will stop by to join our meeting!

Travel information

The meeting will take place in the Singh Center for Nanotechnology, indicated with the red arrow on the campus map below:

Train & bus service:

Intercity rail service to Philadelphia’s 30th Street Station is provided by Amtrak. Frequent service is offered to Northeastern cities including Boston, New York, Baltimore, and the APS DFD meeting in Washington DC. The train to Washington DC takes about 2 hours.

Intercity bus service is provided by Greyhound and Trailway bus lines from the terminal at 1001 Filbert Street, behind The Gallery shopping center. The Penn campus can be reached from the bus station on SEPTA’s Trolley Line (to either 36th and Sansom Streets or 37th and Spruce Streets) or Market-Frankford Line (to 34th and Market Streets).

From the airport:

The Philadelphia International Airport is located in the Southwest section of the city, approximately twenty minutes from the University of Pennsylvania campus. Visitors driving from the airport should take I-95 North to the I-676/Center City Philadelphia exit, which is approximately seven miles North of the airport. Follow I-676 West (the Vine Street Expressway) until I-76 East (the Schuylkill Expressway). Follow I-76 East until Exit 346-A (old exit number 40) — South Street (a left-lane exit). Turn right onto South Street to enter campus.

Convenient train service from the airport to 30th Street Station is available through Septa’s airport line, which leaves every half-hour. The fare is $6.75 (subject to change), and the trip takes approximately twenty-five minutes. To get from the train station to our Physics Department, located in the David Rittenhouse Lab at 209 S. 33rd Street (the SE corner of 33rd and Walnut Streets), climb the stairs at the North end of the platform (i.e., near the front of the train). Walk one block to the West and make a right on 33rd Street.

The 30th Street Station is about a fifteen-minute walk, $10 cab ride, or $3 trolley ride to campus. A metered cab ride from the airport to campus generally costs approximately $40, including the tip, and takes approximately 20 minutes.

Philadelphia public transport:

Philadelphia’s mass transit system is SEPTA, Southeastern Pennsylvania Transportation Authority. SEPTA operates a coordinated system of bus, subway, elevated train, and trolley lines that covers all of Philadelphia and parts of the surrounding counties. Fares are $2.50 cash, and $2.00 with a registered Septa card. Weekly and monthly SEPTA passes are also available. Septa cards can be purchased on campus at the Penn Book Store. Other card kiosk locations can be found on this website, and cards can be registered online for easier card reloading and slightly cheaper fares here.
