These additional trains will supplement normally scheduled local train service on the line.

Broad Street Line trains are scheduled to make the eight mile express trip from Olney to City Hall in less than 15 minutes.

Runners who are officially registered can show their race bib to station cashiers on the line for easy access to trains before and after the race. According to SEPTA, participants in the Broad Street Run may ride the Broad Street Line to the starting line for free the day of the race.
