Westlake/MacArthur Park was constructed by the
Southern California Rapid Transit District, which later became part of today's LA Metro, as part of the first
minimum operating segment (MOS-1) of the Metro Rail subway line. Ground was broken for the project in September 1986. Construction of the short starter line was challenging, and the Westlake/MacArthur Park station was one of the most ambitious parts of the project. Crews built a storage and turnback location for trains under
MacArthur Park. Building the tunnel with a “pocket track” to store subway cars involved completely draining the eight-acre MacArthur Park Lake and digging a
cut-and-cover tunnel. After construction, crews refilled with 20 million gallons of water that required seven days to fill and beautified the entire park, adding a fountain, trees, benches and lighting. The improvements were welcomed by businesses in the area. Before construction began in the late 1980s, MacArthur Park's once glittering reputation had decayed as
gangs and
drug dealers came into the area. The MOS-1 segment along with Westlake/MacArthur Park station opened in January 1993. Ridership on the short line was slow at first, but one major beneficiary of the new line was
Langer's Deli, located about a block away from this station. The subway made it easy for downtown workers to come over to the restaurant for lunch. The owners of Langer's later credited the subway and the improvements to MacArthur Park with saving their business, which had been struggling in the 1980s. Westlake/MacArthur Park station served as the western terminus for trains for three and a half years, until the opening of MOS-2A along
Wilshire Boulevard in July 1996. == Service ==
