I was looking for something Paris Hilton related and came up with this. The corridor runs across the street from the jail where she will be checking in soon. When Paris hears that lonesome whistle it will be coming from one of these trains.
>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 UP line), avoiding more than 200
>at-grade railroad crossings where cars and trucks previously had to
>wait for long freight trains to slowly pass.[3] Many of those same
>rail lines were inadequately protected with little more than
>crossing signals. 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.

>The line went into operation April 15, 2002 and has handled an
>average of 35 train movements per day. It is credited with
>significantly relieving congestion on the Long Beach Freeway (I-710)
>and elsewhere in the region. During the first four months of 2005,
>the line carried 5,434 trains, equivalent to an estimated 900,000
>truck trips that would otherwise have been required.[4]
