London Underground Infrastructure - Lines

Lines

As of 2012, the length of the network 402 kilometres (250 mi). In 1971/72 it was remeasured in kilometres using Ongar as the zero point. The table below lists each line, the colour used to represent it on Tube maps, the date the line became operational and the first section opened (not necessarily under the current line name), the date the line gained its current name (in some cases originally with the word "Railway" rather than "line"), and the type of tunnel used in the central area.

Famous quotes containing the word lines:

    “His more memorable passages are as naturally bright as gleams of sunshine in misty weather. Nature furnishes him not only with words, but with stereotyped lines and sentences from her mint.”
    —Henry David Thoreau (1817–1862)

    “To understand
    The signs that stars compose, we need depend
    Only on stars that are entirely there
    And the apparent space between them. There
    Never need be lines between them, puzzling
    Our sense of what is what.”
    —John Hollander (b. 1929)

    “Was seiz’d by the spirit that trails in the lines underfoot,
    The rim, the sediment that stands for all the water and all the land
    of the globe.

    Fascinated, my eyes reverting from the south, dropt, to follow those slender windrows,
    Chaff, straw, splinters of wood, weeds, and the sea-gluten,
    Scum, scales from shining rocks, leaves of salt-lettuce, left by the tide,”
    —Walt Whitman (1819–1892)
