Description
The project is notable for its "Mid-Corridor Trench", a below-ground, triple-tracked rail line that is 10 miles (16 km) long, 33 feet (10 m) deep and 50 feet wide (15 m), shared by the BNSF Railway and Union Pacific Railroad via trackage rights. The Alameda Corridor allows trains to bypass 90 miles (145 km) of early 20th century branch lines and the Santa Fe's historic Harbor Subdivision along a high-speed grade-separated corridor (mainly built on the alignment of a former SP line), avoiding more than 200 at-grade railroad crossings where cars and trucks previously had to wait for long freight trains to slowly pass. Many of those same rail lines were inadequately protected with little more than "wigwag" crossing signals dating from the original construction of the lines. One important use of the corridor is to take cargo containers to the ports. The corridor has a maximum speed of 40 miles per hour (64 km/h).

Famous quotes containing the word description:
“He hath achieved a maid
That paragons description and wild fame;
One that excels the quirks of blazoning pens.”
—William Shakespeare (1564–1616)
“I was here first introduced to Joe.... He was a good-looking Indian, twenty-four years old, apparently of unmixed blood, short and stout, with a broad face and reddish complexion, and eyes, methinks, narrower and more turned up at the outer corners than ours, answering to the description of his race. Besides his underclothing, he wore a red flannel shirt, woolen pants, and a black Kossuth hat, the ordinary dress of the lumberman, and, to a considerable extent, of the Penobscot Indian.”
—Henry David Thoreau (1817–1862)
“Everything to which we concede existence is a posit from the standpoint of a description of the theory-building process, and simultaneously real from the standpoint of the theory that is being built. Nor let us look down on the standpoint of the theory as make-believe; for we can never do better than occupy the standpoint of some theory or other, the best we can muster at the time.”
—Willard Van Orman Quine (b. 1908)
