-
C.
subway line extension
A subway line extension is an added segment of track and stations that lengthens an existing subway route to serve new areas and increase transit capacity.
-
D.
rapid transit line segment
A rapid transit line segment is a contiguous portion of a rapid transit route between two defined points (such as stations, junctions, or terminals) that carries high-frequency, high-capacity passenger rail service.
-
E.
monorail transit line
