The Metrolink system and its response to the Northridge earthquake are described. Metrolink is part of the Southern California Regional Rail Authority, which was established through a joint-powers agreement among five counties. The sole purpose of the authority is to plan, build, and operate commuter rail service. After the earthquake, key segments of the freeway system were broken and traffic, especially in the north was disrupted. The rail lines fared much better. The Red Line bounced one foot vertically and one foot laterally, but remained relatively undamaged. Surface railroad tracks, especially in curves, moved as much as a foot laterally, but maintained gauge. Immediately after the earthquake Metrolink service was expanded to help maintain mobility. Reassignment of vehicles into the area started immediately. The system was extended to intercept commuters coming from the Antelope Valley. Before the earthquake, daily system ridership was slightly under 1,000. Ridership peaked in the two weeks immediately after the earthquake and then leveled out. Current ridership is about 3,000. A number of capital improvements are being made on the line. In many ways, the earthquake put Metrolink on the map. Whereas about 10% of the residents of Los Angeles knew what Metrolink was before the earthquake, this number is now around 80 or 90%. The response by Metrolink showed that the system could be counted on and that it is an important part of the overall transportation system in the Los Angeles area. |
