LOS ANGELES METRO RED LINE BRIEFING

The article describes progress on the construction of the Los Angeles Metro, with the successful introduction of the first operational Metro Rail Red Line segment, which was opened for commercial service in January 1993, after its design and construction began in 1980 and 1986, respectively. Because of the Metro's size and cost, it has been subject to public debate and scrutiny since its start. Soon after the Red Line was opened, it was found that its tunnels' final concrete lining was not thick enough in several places. As a result, the Metro's owner commissioned an independent team of experts to conduct a review of subway design, including the subway's ability to resist seismic forces, and to review construction to ensure that the final lining met all contract requirements. The report's findings and conclusions are summarised. They are favourable, partly because the tunnels withstood a severe (Richter magnitude 6.8) earthquake in the Los Angeles area on 17 January 1994. The article finally describes work on the construction of Red Line Segment 2, and extensions of Segments 1 and 2.
