This view presents another and clearer image of
the complicated trackwork north of the station at South Hills
Junction. Most runs travel to the left ahead, but the Port
Authority also maintains emergency bypass trackage
that can serve the lines to and from South Hills Village and
Library in the event the Mt. Washington tunnel needs to be closed.
Those tracks, which veer to the right in the photo, go from South Hills Junction up to the Allentown neighborhood,
and then continue down a long grade along Arlington Ave. to rejoin the main routes
on the Panhandle Bridge.
Limited regular passenger service is provided on the lesser-used route in the
form of the 52 Allentown line, which operates just a handful of runs
in each direction during morning and afternoon peak periods.
The route also handles two Beechview trains a day, one in each
direction in the morning and in the afternoon. Going through
Allentown is a short and interesting ride, described further on in this
series.
The tracks to the lower right serve the South
Hills Junction terminal for the 52 Allentown trains. A very few
trains go to and from South Hills Village via Allentown, and utilize the
tracks crossing across the photo from lower left to upper right.
