The Las Vegas Sun reports that, in spite of some hold ups with environmental approvals, work is expected to begin this year on the $4 billion DesertXpress, a high-speed rail link between Vegas and Victorville, California. Construction on the 185-mile project, which involves two parallel, at-grade tracks through the Mojave Desert, mostly along the I-15 corridor, should take four years. Service is scheduled to being in late 2014. Aecom and Stantec have both been involved in the project thus far, along with a slew of engineering companies. The decision to begin/end the line at Victorville has raised some eyebrows. There are advocates who are pushing for an extension to Palmdale—the site of a future high-speed rail link to Union Station—allowing non-stop rail service from downtown LA to Vegas. DesertXpress chose the Victorville terminus because it is the first major population center west of the Cajon Pass, easily accessible to millions of people in the Inland Empire, and could be paid for without recourse to public tax dollars. To date, the project has been entirely privately funded, though it could be eligible for Federal Stimulus money in the future.
