On this chart, nine boxes, linked from left to right, represent the Northeast
Corridor to display the locations of commuter conflicts on the track network
of the Corridor that must be resolved. A legend in the lower right corner lists
the commuter railroad service providers, each represented by a stripe of a different
color. The respective stripes are laid across the boxes to indicate where the
commuter services operate and the potential for conflicts. From the south to
the north the conflict points are:
- (Green) Virginia Railway Express, from Virginia north into Washington, DC,
and connecting to MARC, which is Maryland's commuter rail service.
- (Blue) MARC trains, from Washington, DC to Baltimore to the major intermediate
point between Baltimore and Philadelphia.
- (Gray) Pennsylvania SEPTA trains, from the intermediate point between Baltimore
and Philadelphia (not the same intermediate point served by MARC) to Philadelphia
and beyond Philadelphia and prior to an intermediate point between Philadelphia
and New Haven.
- (Light Blue) New Jersey Transit, from a point prior to the intermediate
station between Philadelphia and New Haven to Harold interlocking. The NJ
Transit commuter trains run parallel to the Long Island Railroad between New
Haven and Harold interlocking.
- (Dark Blue) Long Island Railroad, from an intermediate point between Philadelphia
and New Haven to a point past Harold interlocking and parallel to New Jersey
- (Blue) Metro North Commuter Railroad, four stripes (tracks) linking New
Rochelle to New Haven, Connecticut.
- (Red) Connecticut's Shore East commuter services originate in New Haven,
Connecticut, and travel north to a point between New Haven and Providence,
- (Magenta) Massachusetts Bay Transit Authority, from Providence, Rhode Island,
to Boston, Massachusetts.
