Desert Xpress

Rail Surveyors and Engineers (RSE) provided survey and mapping for the 193-mile XpressWest high speed rail corridor along Interstate 15 from Victorville, CA to Las Vegas, NV. RSE utilized Survey Grade GPS technology to perform the control surveying. It is a challenge for any project team in setting a control network to meet mapping accuracy requirements within a demanding schedule of seven weeks. Due to the length, remoteness, and required efficiency of the project RSE planned its approach to ensure the best possible quality and precision of the control network.

CHSRA finds California Rail Builders as the apparent best value

The California High-Speed Rail Authority (CHSRA) has identified California Rail Builders as the apparent best value proposer for the design-build services contract for Construction Package 4, the next segment of construction through the counties of Tulare and Kern and the cities of Wasco and Shafter.



Caltrain: San Mateo Bridges Replacement Project

RSE was the primary firm to design the four rail bridges in the northern part of San Mateo at Tilton Avenue, Monte Diablo Avenue, Santa Inez Avenue, and Poplar Avenue. These four bridges were built in 1903 and did not meet current Federal and State seismic safety standards. Caltrain is launching a bridge replacement project to bring these bridges up to current standards, and will span a half-mile along the Caltrain right-of-way from Tilton Avenue to Poplar Avenue.
