# California High-Speed Rail – United States

![California High-Speed Rail – United States](https://www.systra.com/wp-content/uploads/2024/03/california-lgv.jpg)

**California High-Speed Rail is a high-speed rail line being implemented by the California High-Speed Rail Authority (CAHSRA). Its aim is to reduce journey times, particularly between the San Francisco Bay Area and Greater Los Angeles, as well as cutting carbon emissions, easing congestion on highways and air traffic, and boosting the state’s economy, particularly in the Central Valley region.**

### A LONG-TERM PROJECT

SYSTRA has been working on this project since 2006, when it was subcontracted by
Parsons Brinckerhoff. Since 2019, as a subcontractor of the Canadian engineering
firm Stantec, we have been involved in supervising all aspects of systems
engineering, carrying out preliminary studies of the rail systems, and
supporting the preliminary structural studies of two bridges.

### EXTENDING THE LINE’S ROUTE

At the end of 2022, SYSTRA increased the scope of its assignments and is now an
integral part of the consortium in charge of designing the section between
Merced and Madera (known as the M-M section) on the future high-speed line (HSL)
in California, in the Central Valley area. We are responsible for carrying out
the design studies for the route of the line, with the option of delivering the
final design studies and preparing the documents to launch construction.

The purpose of these assignments is to advance the construction of the HSL to
Merced in the north and Bakersfield in the south, as an extension of the portion
already built in the Central Valley, i.e. a stretch of 84km to be added to the
275km already built.

The commissioning of the line is scheduled for 2030.
