|This scene, photographed from the approach to
Smithfield Bridge, shows a train leaving the transit tunnel under
Mt. Washington. That tunnel serves both light rail and
numerous bus lines. The train will stop at Station Square,
just out of sight to the left, and then will begin the rise to cross over
the Monongahela River on Panhandle Bridge.
Pittsburgh made extensive changes to its trolley service in the
mid-1980s as it converted the remaining lines of its once-huge
system to a much more modern operation. Prior to the changes,
the PCC trolleys from the south continued out of the tunnel on a
much straighter course across Smithfield Bridge, behind the camera, to reach downtown.
