The pointy roof of the Evans City Junction depot on the Harmony Line can be seen in a 1910 photo that demonstrates how busy the depot was. The borough's historical society is now trying to buy the depot. Submitted Photo

A small building on a busy borough street that is passed by hundreds of disinterested motorists and pedestrians each day holds uncounted secrets of Evans City’s transportation history, and now it looks like the historical society will be able to save it.

The former Harmony Line trolley depot has stood vigil for more than 100 years on a triangular spit of pavement surrounded by South Washington Street, Jefferson Street and Center Alley.

Rita Reifenstein, corresponding secretary on the Evans City Historical Society board of directors, said the building was erected in 1909 and served as the trolley depot until 1931, when the trolley line closed.
