and a failure to account for maintenance costs. The contract for 175 cars (the first two phases) was signed by Mayor Ed Lee in September 2014, making the cost of each car approximately . Muni ultimately purchased 249 vehicles: the 175 cars from the first two phases, 44 additional cars, and surplus 30 cars were contracted in 2021. Design Siemens has named the new Muni cars the S200 SF while the SFMTA refers to them as the LRV4. They operate at speeds of up to . The S200 SF is long, wide, high (with the pantograph locked down), and weighs , making it comparable in size and weight to the existing Breda cars. The expected maximum capacity is 203 passengers per car. They are expected to have the same coupling device as the Breda cars; however, the new Siemens trains can couple up to five cars at a time. The new S200 SF vehicles are projected to be able to run between maintenance intervals. Initially, the new cars had a mean distance between failures (MDBF) of shortly after being delivered; by August 2019, the MDBF had improved to . Service history Siemens publicly unveiled a full-size mockup of the S200 SF in San Francisco on June 16, 2015. The first car was delivered from the Siemens plant in Sacramento to San Francisco on January 13, 2017. A test car passed a CPUC regulatory inspection in early November 2017 and car #2006 was the first LRV to enter revenue service on November 17, 2017, following a ribbon-cutting ceremony at Duboce and Church. The first 68 cars were used to expand the Muni fleet to 219 cars and once the fleet reached that total in October 2019, Breda cars would be retired as new Siemens cars are accepted. It is expected that deliveries of cars will continue through 2028.
