At all local stations (except at 110th Street and Lenox Avenue) the

Platforms_]

At express stations there are two island platforms between the express
and local tracks, one for uptown and one for downtown traffic. In
addition, there are the usual local platforms at Brooklyn Bridge, 14th
Street (photograph on page 34) and 96th Street. At the remaining
express stations, 42d Street and Madison Avenue and 72d Street, there
are no local platforms outside of the tracks, local and through
traffic using the island platforms.

The island platforms at Brooklyn Bridge, 14th Street, and 42d Street
and Madison Avenue are reached by mezzanine footways from the local
platforms, it having been impossible to place entrances in the streets
immediately over the platforms. At 96th Street there is an underground
passage connecting the local and island platforms, and at 72d Street
there are entrances to the island platforms directly from the street
because there is a park area in the middle of the street. Local
passengers can transfer from express trains and express passengers
from local trains without payment of additional fare by stepping
across the island platforms.

At 72d Street, at 103d Street, and at 116th Street and Broadway the
