A train destined for South Hills
Village descends from bridge level toward Station Square in this
photo taken through the front window of a Pittsburgh-bound train.
The two main "T" lines carry route numbers identifying whether the
cars utilize the Beechview corridor, 42, or the Overbrook route, 47.
The identification scheme now further carries a letter designator. An
ending "S" indicates
service to and from South Hills Village. An "L"
denotes service to and from
Library. The letter "C" is used for Beechview trains ending at
Overbrook Junction in Castle Shannon. As South Hills trains run on both corridors, there
are four resulting resulting route possibilities: 42S, 42C, 47S and 47L.
