This photograph of the Great Soho Curve, a maintenance nightmare for the cable cars that very briefly made up Pittsburgh’s transit system, was taken in 1893. It appears to have been taken from the roof of a house about where the ramp from Fifth Avenue to the Boulevard of the Allies is today. Fifth Avenue still makes this double curve, though the street is one-way inbound now, and the cable cars are gone.

This picture tells the story of why we don’t have cable cars anymore. Pittsburgh streets have curves, and curves are bad for cable cars. In this picture, the entire curve is lined with cable access points about every six feet, and the picture shows cars stopped while men are fussing with one of the cables. In San Francisco, the one city where cable-car lines are still in service, the lines are all perfectly straight, except for turns at intersections. When electric traction came along, it was obviously more suitable for Pittsburgh—except where hills were prohibitively steep, and for those places we have inclines, which are a kind of cable car permanently attached to the cable.

That fairy castle on the hill at upper left is the Ursuline Young Ladies’ Academy, designed by Joseph Stillburg. It has long since been replaced by more mundane buildings at Carlow University, but this picture shows the impression it must have made as you rode the cable car out from downtown toward Oakland.
