Lone Hill Av to White Av Double-Track
Metro is adding a second mainline track between Lone Hill Avenue in San Dimas and White Avenue in La Verne to improve Metrolink service. The project upgrades crossings for safety and supports future Quiet Zones.
Metro’s transit improvement plan includes adding a second mainline track along a 3.9-mile segment between Lone Hill Avenue in San Dimas and White Avenue in La Verne. The project also includes “Quiet Zone Ready” upgrades to roadways and sidewalks, new and upgraded track and pedestrian crossing equipment, and improvements to drainage and landscaping.
The second mainline track will allow opposing trains to operate on separate tracks, enhancing the flow of both Metrolink and Union Pacific trains while improving on-time performance and schedule reliability.
The existing railway, owned by Metro, is part of the San Gabriel Subdivision and serves both Metrolink commuter rail (approximately 38 trains daily) and Union Pacific Railroad freight service (up to four trains daily).
