The South Hills Junction

South Hills Junction - 1906

This is the Pittsburgh Railways South Hills Rail Junction as it looked in the fall of 1907, nearly three years after the Mount Washington Transit Tunnel opened to traffic. All streetcar, and later bus, traffic to and from the South Hills communities came through this tunnel. It was then, and may always be, one of the busiest intersections in the city.

In the photo above, taken from atop the transit tunnel entrance, a Pittsburgh and Castle Shannon Railroad outbound passenger train can be seen chugging along the Warrington Avenue hillside in the distance after clearing the horseshoe curve. Prior to 1904, this low-guage railroad, once used primarily to ship coal to the city, was for many years the best transportation alternative offered to commuters traveling into Pittsburgh from the south.

The junction actually had its beginnings a few years before, at the turn of the century, as a transit hub where the Mount Lebanon horse-drawn line met with the Warrington Avenue line. It was also near the Castle Shannon South Incline passenger station.

The billboard on the hillside showcases a Freehold Real Estate advertisement touting Fourth Ward lot sales in the fast growing suburb of Brookline. The transit tunnel and subsequent 39-Brookline trolley service shortened the trip from the community of Brookline to downtown Pittsburgh from a matter of hours to only fifteen minutes.

As a result, land speculation, real estate development and property valuations in Brookline, as well as other South Hills communities, saw exponential growth.

For over a century, there has been a constant stream of trolleys, buses and light-rail cars rolling by on their way to Brookline, Beechview, Carrick, and numerous other destinations in the South Hills. The transit tunnel, built under Mount Washington, was one of the major engineering achievements from the early 20th century. It spurred the southward expansion of the City of Pittsburgh and the birth of the community of Brookline.
