Antelope Valley Line Capacity and Service Improvements Program Project Map

Metro has a plan to make it easier to get around with increased rail service along the entire Antelope Valley Line (AVL) corridor. In collaboration with Metrolink and local jurisdictions, this program focuses on targeted infrastructure improvements to support more frequent, reliable train service between Union Station and Lancaster.

The effort includes extending track segments, upgrading terminals, and expanding storage capacity—enhancing the corridor’s ability to serve growing communities across the San Fernando Valley, Santa Clarita Valley, and Antelope Valley. Key project elements include:

A double track extension near Balboa Boulevard to improve service flow and reduce bottlenecks
A siding extension and safety enhancements near Golden Oak Road in Santa Clarita
Terminal upgrades in Lancaster, including additional layover tracks, pedestrian improvements, and operator facilities

To address community concerns and evaluate broader cumulative impacts, Metro conducted a full Environmental Impact Report (EIR), finalized in 2021.
