Track
For the permanent way Brunel decided to use a light bridge rail continuously supported on thick timber baulks, known as "baulk road". Thinner timber transoms were used to keep the baulks the correct distance apart. This produced a smoother track and the whole assembly proved cheaper than using conventional sleepers for broad-gauge track, although this advantage was lost with standard- or mixed-gauge lines because of the higher ratio of timber to length of line. More conventional track forms were later used, although baulk road could still be seen in sidings in the first half of the twentieth century.

Famous quotes containing the word track:
“I was the conductor of the Underground Railroad for eight years, and I can say what most conductors can’t say—I never ran my train off the track and I never lost a passenger.”
—Harriet Tubman (1821–1913)
“What is the use of going right over the old track again? There is an adder in the path which your own feet have worn. You must make tracks into the Unknown.”
—Henry David Thoreau (1817–1862)
“It is remarkable how easily and insensibly we fall into a particular route, and make a beaten track for ourselves. I had not lived there a week before my feet wore a path from my door to the pond-side; and though it is five or six years since I trod it, it is still quite distinct. It is true, I fear, that others may have fallen into it, and so helped to keep it open.”
—Henry David Thoreau (1817–1862)
