The purchase of Muni’s next metro train fleet took a major step forward today as the the SFMTA Board of Directors unanimously approved a manufacturing contract with Siemens.
Muni officials lauded the design of the new trains as far superior to the current, abysmally breakdown prone fleet of light-rail vehicles, which were built by AnsaldoBreda. The fleet of 260 new trains will be manufactured by the German company Siemens at its Sacramento factory, and will roll out over several years starting at the end of 2016.

The SFMTA Board authorized the agency to spend up $1,192,651,577 to purchase up to 260 Siemens trains, to be rolled out in phases by 2028. The first batch of 24 trains is expected to be phased in from the end of 2016 to 2018, and thus ready in time for the completion of the Central Subway in 2019.
Haley called Siemens an “industry leader,” and said the company has a proven record, with about 1,300 of its trains used by North American transit systems. He said that Siemens has a “strong and consistent track record of meeting delivery schedules.”

The new models will come with several variations, and will be able to couple with Breda trains — which will continue to run in conjunction with Siemens trains for years, until the current fleet is completely retired. Haley noted that the train cars will also be able to couple and de-couple easily, and allow Muni to run trains as long as four cars long.
