Due to the difference in tunnel clearances, the IRT and BMT/IND
lines are operated separately. However there are some places where the
former IRT lines and former BMT/IND lines connect. These are mostly
used for work and revenue collection trains (which are IRT sized), and
for moving IRT passenger cars to shops on the IND/BMT lines (Coney
Island Overhaul, 207th Street Overhaul) for maintenance.
The connections are:
A one-track connection between the IRT #3 (New Lots Line) and
the BMT "L" Canarsie line near the Junius St. Station, for Linden Yard
access. There is no third rail on this connection. The yard is
normally used for work trains powered by diesel locomotives.
A diamond crossover on the upper level of Queensboro Plaza,
between the N and the 7. This connection is the #7 line's sole
connection to any other line in the system and is used for bringing #7
cars on and off the line for maintenance (or delivery of new
cars).
Yard leads connect the Concourse Yard to the #4 line just north
of Kingsbridge Road station and to the Concourse Subway just south of
205th Street.
Yard leads connect the 207th Street Yard to the #1 line north
of 207th St station and to the 8th Avenue IND subway.
