Pleasant Street incline in
Boston • Northeast U.S. (
Amtrak) • Along the
New York–
Washington section of the
Northeast Corridor, and on the Philadelphia–
Harrisburg section of the
Keystone Corridor. Both converge at
Zoo Junction near
30th Street Station in Philadelphia. All were built by the former
Pennsylvania Railroad and are now maintained by Amtrak. •
Boston, Massachusetts area • An abandoned underground junction on the
Tremont Street subway approaching the
Pleasant Street incline • The B branch splits off from the C and D branches of the
MBTA Green Line via an underground flying junction just west of
Kenmore station. • The Union Square spur splits off from the
Green Line Extension of the
MBTA Green Line via an aerial flying junction on the Red Bridge viaduct in the Inner Belt area of
Somerville, Massachusetts just north of
Lechmere station in Cambridge. Lead tracks to the GLX maintenance facility also split off from the junction slightly further west. • The two southern branches of the
MBTA Red Line in Boston split via a flying junction just north of
JFK/UMass station. In addition, lead tracks to Cabot Yard maintenance facilities branch off from the junction. •
Chicago, Illinois • On the
Chicago "L", where
Orange Line trains diverge from

Red Line trains heading to
95th from those heading to the
South Side main line, which is occasionally used for emergency reroutes to
Ashland/63rd. • The
Milwaukee–Dearborn subway (now part of the
Blue Line) was constructed to have a flying junction where turning between Lake Street and Milwaukee Avenue at Canal Street. The outbound tunnel and its stub, designed to continue west under Lake Street, was bored at less depth than the inbound tunnel and its Lake Street stub, in order to allow future Lake Street trains (now part of the
Green and (
Pink Lines) to run under or over the opposing Milwaukee Avenue trains while entering or exiting the shared portion of the Lake Street tunnels. Plans in 1939 called for tunnels to replace the elevated Lake Street tracks east of approximately Racine Avenue. By 1962, the planned Lake Street tunnels to/from Racine Avenue would have curved south to Randolph Street and bypassed the Milwaukee-Lake-Dearborn tunnel entirely. • A flying junction immediately north of
Belmont/Sheffield is used by
Brown Line trains to access the
Ravenswood Branch while avoiding crossing the Red Line and
Purple Line Express tracks. •
Denver, Colorado • On the
Regional Transportation District in Denver between the Southeast Corridor and the I-225 Corridor: the Southeast Corridor is on the west side of I-25 and the I-225 Corridor is in the median of I-225.

There are also flying junctions near three underground rail stations: Rosslyn (Blue, Silver, and Orange Lines), L'Enfant Plaza (Green and Yellow lines), and the Pentagon (Blue and Yellow lines). ==See also==
