The LRT alternatives would be similar to the Metro Gold Line and Metro Blue Line currently operated by Metro in Los Angeles County. LRT systems typically operate along dedicated rights-of-way at-grade, but can be built in aerial or underground configurations where necessary. They are electrically powered through an overhead catenary system. In dedicated right-of-way, Metro LRT vehicles can operate at speeds of up to 65 mph. The LRT alternatives include all of the additional transit service provided in the TSM/TDM alternative, except where those services overlap with the LRT service itself. The LRT alternatives are illustrated in Figure ES-5.
LRT-4A. Alternative LRT-4A would begin at an aerial station on Mednik Avenue adjacent to the existing East LA Civic Center Station on the Metro Gold Line. It would remain elevated as it travels north to a station adjacent to Cal State LA, then descend into a tunnel north of Valley Boulevard and end at an underground station beneath the existing Fillmore Station on the Metro Gold Line.
LRT-4B. Alternative LRT-4B was developed as a design variation of Alternative LRT-4A to reduce the length of tunneling required. Alternative LRT-4B would follow the same path as Alternative LRT-4A to the Cal State LA Station. Instead of immediately entering a tunnel, Alternative LRT-4B would continue on an elevated structure above Mission Road, turning north on Palm Avenue where it would descend to grade on Palm Avenue. Alternative LRT-4B would then enter a bored tunnel before Main Street and continue along an alignment similar to that of Alternative LRT-4A.
LRT-4D. Alternative LRT-4D was developed as a design variation of Alternative LRT-4A to eliminate the bored tunnel section and use only cut-and-cover tunnel techniques. Alternative LRT-4D would originate at an underground station beneath Beverly Boulevard, near the existing Atlantic Station on the Metro Gold Line and end at an underground station beneath the existing Fillmore Station on the Metro Gold Line.
LRT-6. Alternative LRT-6 would connect the existing Atlantic and Fillmore stations on the Metro Gold Line. Alternative LRT-6 would begin at an aerial station on Atlantic Boulevard near Pomona Boulevard and terminate with a new, elevated station above the existing Fillmore Station on the Metro Gold Line. The alternative would consist of at-grade and aerial segments.
