Project Description

The 76.6 -mile long AVL commuter rail corridor between Lancaster and downtown Los Angeles is anticipated to experience strong population and employment growth over the next 20 years. Solutions to realize the full potential of this corridor are crucial to support the increase in growth. Currently, around 66% of the AVL corridor is single track, meaning that only one track is provided to operate trains in both directions. This limits the ability to run more frequent services and a regularized schedule, especially during the off peak and weekends.

In addition to track limitations there are constraints with maintenance and storage facilities at the Lancaster Station Terminal. This project will help facilitate plans to improve service frequency and reliability to communities along this 76.6 miles of commuter rail.

Scope of Services

RSE provided track alignment alternative study and prepare conceptual engineering plans for this 76-mile rail corridor from Los Angeles Union Station to Lancaster. The engineering work involved the design of new track alignment alternatives to accommodate future high-speed rail and double track in various locations to increase rail capacity. The engineering work required close coordination between the stakeholders including XpressWest, Metrolink, UPRR, and LA Metro. RSE also analyzed the track sections to determine right of way impacts, requirements of new bridges, boring new tunnels, and relocation of a station.
