Mixing Double and Single Track
Because double and single track may use different signalling systems, it may be awkward and confusing to mix double and single track too often. For example, intermediate mechanical signal boxes on a double-track line can be closed during periods of light traffic, but this cannot be done if there is a single-line section in between. This problem is less serious with electrical signalling such as Centralized traffic control.

Famous quotes containing the words single track, mixing, double, single and/or track:
“It may seem strange that any road through such a wilderness should be passable, even in winter, when the snow is three or four feet deep, but at that season, wherever lumbering operations are actively carried on, teams are continually passing on the single track, and it becomes as smooth almost as a railway.”
—Henry David Thoreau (1817–1862)
“Give me Catholicism every time. Father Cheeryble with his thurible; Father Chatterjee with his liturgy. What fun they have with all their charades and conundrums! If it weren’t for the Christianity they insist on mixing in with it, I’d be converted tomorrow.”
—Aldous Huxley (1894–1963)
“O, my offense is rank, it smells to heaven;
It hath the primal eldest curse upon ‘t,
A brother’s murder. Pray can I not,
Though inclination be as sharp as will;
My stronger guilt defeats my strong intent,
And like a man to double business bound
I stand in pause where I shall first begin,
And both neglect. What if this cursed hand
Were thicker than itself with brother’s blood,
Is there not rain enough in the sweet heavens
To wash it white as snow?”
—William Shakespeare (1564–1616)
“Ever fresh the broad creation,
A divine improvisation,
From the heart of God proceeds,
A single will, a million deeds.”
—Ralph Waldo Emerson (1803–1882)
“To most men, experience is like the stern lights of a ship, which illumine only the track it has passed.”
—Samuel Taylor Coleridge (1772–1834)
