SEPTA's "Great Valley Flyer" races past Bryn Mawr tower and a surviving PRR signal position light while en route to Paoli, PA and eventually Thorndale. The pantograph of a second AEM-7 can be seen behind the first Bombardier car. SEPTA's express "Great Valley Flyer" can sometimes be captured here in a meet with another push/pull set as it makes a station stop as seen here.
