SCORE Phase I – San Bernardino Line – Marengo Siding

In light of the demand on Southern California highways, Metrolink developed the Southern California Optimized Rail Expansion (SCORE) program, which will upgrade the regional rail system to meet the current and future needs of the traveling public.  Metrolink hopes to provide a viable alternative to single-occupancy vehicles by implementing improvements along its entire system so that trains operate more frequently and more reliably.

Zephyr Rail (ZUI) is participating in this program as a sub-consultant under the STV/Jacobs Joint Venture, which is tasked with SCORE Phase I for the San Bernardino Line.  Under this contract, ZUI is taking charge of studying the viability of a 4000-ft extension of Marengo Siding, near Cal State LA, which will allow for continuous train movement through the area.  ZUI will study different alternatives, develop plans, and prepare a Preliminary Design Report for the extension.
