New Light Rail Vehicles for Central Subway

New light rail vehicles (LRVs) are being built in Sacramento by Siemens for the city of San Francisco. The first of the vehicles is anticipated to make its way from Sacramento to San Francisco in late 2016. The expansion of the light rail fleet comes at just the right time with the T Third Line extension opening for revenue service in 2019.

A video posted by Siemens entitled, “How do we move California?” gives a quick look at the new LRVs. This press release highlights some of the benefits of the LRVs such as less down time for maintenance and better vehicle reliability.

The new vehicles are based on a model known as S200 SF. The rendering shows what the new trains may look like.
