There are 3 main rapid transit lines
in the city transit system, the Market-Frankford El, the Broad St
Subway and PATCO.
The heavily
patronized Market-Frankfort El received new rolling stock in 1999,
replacing the famous Budd "Almond Joy" cars. In August of 2004
the original Frankford Terminal was demolished for the new Frankford
Transportation Center which is located near the original terminal. The
El in West Philly is being completely rebuilt.
The Broad St
Subway is designed for high capacity with many branches. One branch
has been built (Ridge St. Spur). The 4 track main line north of Locust
is similar to NY's famous subway lines. In the early 90's the express
track was finally extended to Olney (roadbed was in place, just no
tracks). Hopefully someday this line will meet its full potential.
PATCO is a separate system that uses the original
Bridge Line
