S200 SF Light Rail Vehicle, San Francisco, California, United States of America


Siemens S200

Siemens' S200 SF Light Rail Vehicle (LRV) is a sleek and light-weight train being manufactured to ply on the San Francisco Municipal Transportation Agency's (SFMTA) Muni Metro, the third-busiest light rail system in the US.

The Muni transit system is currently served by a fleet of 151 LRVs, which will be replaced by the S200 SF LRVs. Siemens will supply 260 S200 SF LRVs in total to provide improved services and help meet the Muni transit system's expected passenger growth of more than one million a day by 2040.

The first trainsets in the series is expected to be delivered in late-2016 and start operations in 2017. They are being manufactured at Siemens' solar-powered rail manufacturing plant in Sacramento, California.

S200 SF LRV design details



San Francisco Bay Area Rapid Transit District (BART) will replace its fleet of existing 669 rail cars, which are the oldest in the country, with 775 new rail cars under a project known as the Fleet of the Future.


Nased on Siemens' Model S200, the S200 SF LRV is a hybrid train integrating Siemens' high-floor and low-floor light rail platform technologies.

Each trainset is 22.86m-long, 2.65m-wide, approximately 3.5m-high with its pantograph locked down, and has an entrance height of 0.864m.

Each train has a capacity to accommodate 60 seating passengers and 203 total passengers. Up to four wheelchair spaces or bicycle areas are featured in each train.

The exterior design and interior layout of the new fleet are based on the input and feedback from more than 8,000 Muni passengers. The Skyline design was selected for its exterior in place of the other two additional designs namely the Presidio and the Gate.

Propulsion and performance

"Equipped with Siemens proven IGBT propulsion system, the light-weight drive system of the train will be capable of recovering the braking energy."

Equipped with Siemens proven IGBT propulsion system, the light-weight drive system of the train will be capable of recovering the braking energy.

The maximum operational speed of the train is 50mph (80.5km/h), whereas the maximum allowable speed is 55mph (88.5km/h).

Energy-efficiency and safety features

The train will be equipped with state-of-the-art heating, ventilation and air conditioning (HVAC) equipment control systems to save energy and reduce operating costs. Both the interior and exterior of the train will be equipped with energy-efficient LED lighting system.

The doors are designed with fewer parts and the train's serviceable components can be easily disconnected, replaced and reconnected, alleviating the repair process. It is designed to travel for up to 59,000 miles without repair, compared to the existing LRVs, which require repairs after every 5,500 miles covered.

The carbody is designed to improve crashworthiness and operator protection. The enhanced visibility for the train operator will ensure safety for pedestrians and cyclists, while the train's hydraulic brakes have the fastest reaction time possible, reducing the braking distance.

S200 SF Light Rail Vehicle (LRV) orders and financing details

"The first option was exercised by making an order for 40 additional trainsets, valued at $210m, in January 2015."

SFMTA awarded Siemens the initial order for 175 LRVs, valued at $648m, with options to further order 85 additional trainsets in two instalments, in September 2014.

The first option was exercised by making an order for 40 additional trainsets, valued at $210m, in January 2015. SFMTA expects to source $153m from the California cap-and-trade funds and the remaining $57m from its own revenues.

A grant of $41.1m was awarded to SFMTA by the California State Transportation Agency in new cap-and-trade funds, as part of the Transit and Intercity Rail Capital Program (TIRCP), in June 2015.

The project is also being funded through other sources including the Federal Transit Administration's (FTA) Central Subway Project funding sources, the Prop 1B State Bond, the San Francisco County Transportation Authority's (SFCTA) Proposition K funds, and grant funds arranged by the Metropolitan Transportation Commission (MTC).
