A late afternoon SEPTA push-pull set arrives at Overbrook station. To the right is Overbrook Tower, which was built in 1927, and is still in service today- in fact, it controls the switches seen in the foreground. In a set up similar to Bryn Mawr,, crossovers are located between the platforms meaning you will not see a fence separating the ROW. Passengers, however, are expected to the the subterranean walkway, the stairway entrance can be seen to the far left.
