An eastbound set of SEPTA Silverliner IV's arrives at Paoli, passing a westbound, and Paoli Tower, which was built by the Pennsylvania Railroad in 1896.
PAOLI was an intermediate design between the generation of all wood towers and the later PRR standard all-brick towers. The tower was once fully surrounded by full length double hung windows that have since been boarded over. It also had a curved oriel window that once projected from the second story on the side facing the main line tracks was destroyed, supposedly in a crash in the late 1960s, and was never replaced. The tower is currently still in operation.
