Flying Junction

A flying junction or flyover is a railway junction at which one or more diverging or converging tracks in a multiple-track route cross other tracks on the route by bridge to avoid conflict with other train movements. A more technical term is "grade-separated junction". A burrowing junction or dive-under is where the diverging line passes below the main line.

The alternative to grade separation is a level junction or flat-junction, where tracks cross at grade and conflicting routes must be protected by interlocked signals.

Famous quotes containing the words junction and/or flying:

    In order to get to East Russet you take the Vermont Central as far as Twitchell’s Falls and change there for Torpid River Junction, where a spur line takes you right into Gormley. At Gormley you are met by a buckboard which takes you back to Torpid River Junction again.
    Robert Benchley (1889–1945)

    He was last seen flying to New York.
    He was handing out cards which read:
    “He wears a question in his left eye.
    He dislikes the police but will associate with them.
    He will demand something not on the menu.
    He is invisible to the eyes of beauty and culture....”
    John Ashbery (b. 1927)
