An eastbound Amtrak Keystone arrives at Paoli, passing Paoli Tower, which was built by the Pennsylvania Railroad in 1896. The station is just ahead, its platforms now occupying the location of the two inside tracks.
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.
