Train service will be replaced by bus shuttles on the Expo Line the weekend of February 24, 25 and 26 so that maintenance and repair work can be performed on overhead wires, train tracks and communications equipment, the Los Angeles County Metropolitan Transportation Authority (Metro) announced. • From 9 p.m. Friday, Feb. 24, through Sunday, Feb. 26, express and local bus shuttles will replace train service between Expo/Sepulveda Station and Downtown Santa Monica Station. Trains and buses will follow their regular schedules. Maintenance work and bus shuttle service will begin at 9 p.m. on Friday and continue through the end of service on Sunday. Twenty Metro buses will be used to ensure bus service is quick with plenty of capacity. The contractor that built the project Skanska/Rados Joint Venture has one year to fix items on the line that require repair or replacement. In order for the work to be done safely, the overhead wires that deliver electricity to trains must be powered down. Among items that need work: replacing and relocating closed circuit television cameras near the overhead wires, adjustment of power cable counterweights and localized track work. Metro also will use the closures as an opportunity to perform state of good repair maintenance work on the Expo Line. Metro officials said that performing the work over the weekend would be the quickest way to get the work done and cause less inconvenience to the riding public.
