Siemens S700 and S70

The first order for S70 vehicles in the U.S. – where the three-section model was originally known as S70 Avanto but soon became known simply as the S70 – was placed in 2001 for the METRORail system in Houston, Texas, and the first car was received by Houston in April 2003. This first series of S70 cars entered service on January 1, 2004, the opening day of Houston's light rail system. At Siemens's U.S. manufacturing facilities (in Sacramento, California), only the model S700 remains in production, the last S70s having been built in 2017, for Minneapolis–Saint Paul's Metro Transit light rail system. The first purchase of the European version, a five-section tram-train design sold under the Avanto brand name, was a 15-car order placed in July 2002 by SNCF, for its line between Aulnay-sous-Bois and Bondy, which is now known as Île-de-France tramway Line 4. S700 redesign and model number change The model number S700 was adopted by Siemens Mobility in 2019 as a rebranding of a version of the S70 that had been in production since 2014. Versions later branded as the S700 used an adapted form of Siemens' model SF 40 center truck, first used in its SD660 model (first built in 1996 for Portland, Oregon's MAX Light Rail system) to the S70. This truck allowed longitudinal (sideways-facing) seating to be used in the center section, in place of the transverse seating used in the S70. The design change provided better passenger comfort and movement. The first LRVs built to the newer design were the "Type 5" cars for the MAX Light Rail system, in 2014. Initially Siemens continued to sell LRVs with either center-section configuration and used the designation S70 for both. In 2019, the company began using the designation S700 for new orders, and in 2020 it retroactively applied the S700 designation to all LRVs and streetcars that had been built to the newer design since its creation in 2013 or 2014. == Size and configuration ==

The S70, S700, and Avanto have a modular design and can be built in a number of different sizes and configurations, including both light-rail vehicle (LRV) and streetcar versions. The standard version of the S70 and S700 LRV is long, although the earliest S70 units delivered had a different, longer cab design that extended the length to . The streetcar version of the S700 is long, about shorter than the standard LRV. Siemens also offers a US ("Ultra Short") variant of the LRV at , about shorter than the standard version. All versions of the S70 and S700 have the suspended articulation construction. The major change between the S70 and the S700 is the seating in the center section of the vehicle. The S700 has longitudinal seating in this section with passengers facing the aisle, while the S70 had more traditional seating with passengers sitting four-across, facing forward or back, with an aisle in between. This 2013 change, which was made to eliminate a seating layout that had been criticized as cramped and ease the movement of passengers within that section, was the primary design change that led Siemens eventually to adopt (in 2019) the new model number for the modified S70 design. TriMet reverted to a double-ended design for its latest order of S700s (placed in 2019). The S70, S700 and Avanto can be configured to operate on various overhead power supply systems. For example, the Avantos ordered for France are dual voltage, capable of operating on 750 V DC when running on tram or light rail tracks and on when running on main line tracks. Systems in the Americas most commonly use the 750 V DC system, but S700s are used on 600 V DC in San Diego and on 1500 V DC in Seattle. On the CityLynx Gold Line in Charlotte, the vehicles are additionally equipped with onboard batteries. The S70 and S700 can also be equipped to interface with older Siemens light rail vehicles. The San Diego Trolley's S70 and S700 vehicles frequently operate with high-floor SD-100 vehicles. == Usage and current orders ==

United States • Atlanta, Georgia (Atlanta Streetcar): 4 S70 Streetcar units, ordered in 2011. In May 2011, Siemens announced that it had won the $17.2 million contract to build the four streetcars that run on the Atlanta Streetcar. The vehicles were built at Siemens' plant in Florin, California, but with major components, including the propulsion system, assembled at Siemens' plant in Alpharetta, Georgia. The first of the streetcars was delivered on February 17, 2014, and began passenger service on December 30, 2014. • Charlotte, North Carolina • Lynx Blue Line: 42 S70 units purchased and now operating. First 16 cars, purchased for $50 million, have been in service since the opening of the Charlotte light rail system in November 2007. Four additional units purchased in 2008 to keep up with higher-than-expected ridership were received in early 2010. In 2012, after 4 years of operation, the original 16 cars had to be repaired at the Siemens facility in California for an estimated cost of $400,000 each. The S700 streetcars are a compact version of the S70 light rail vehicles that currently operate on the LYNX Blue Line. The cost to purchase these six vehicles and spare parts is $40.4 million. • Houston, Texas (METRORail): 18 S70 units purchased, the first of which was delivered in April 2003; delivered starting in late 2012. The original cars are the long variant; the 2012–13 cars are the US ("Ultra Short") variant. 14 more S700 units were ordered in early 2019. • Minneapolis–Saint Paul, Minnesota (Metro): 64 S70 units purchased. Delivery of initial order of 59 began in 2012, with the first unit entering service in February 2013.
