Siemens S70 car for the LYNX Blue Line in Charlotte, North Carolina

The Siemens S70 or Avanto is a low-floor light rail vehicle (LRV) or tram manufactured by Siemens AG. In the United States, Siemens refers to this model only as the S70,[1] while the Avanto name is used in Europe.

The S70 is in use, or on order, by several light rail systems in the United States.

In Europe, Siemens Combino and Avenio models are the preferred offerings for purely light rail or tramway systems, and the Avanto is principally sold to tram-train systems which, in whole or part, share their tracks with heavy rail trains. Here its principal competitors are Bombardier’s Flexity Link tram-train and Alstom’s Citadis Regio-Citadis/Citadis-Dualis tram-train variants. To date, the Avanto has been sold to two tram-train operations in France.[2]

Size and configuration[edit]

Diagram of the Siemens S70

The S70/Avanto has a modular design and can be built in a number of different sizes and configurations. The Light Rail Vehicle version is 9 feet longer than the US Version[clarification needed][citation needed] and the upper seats are facing to the cab, while the Streetcar version is shorter with the upper seats facing the doors of the train.[citation needed] In addition, the horn on the light rail vehicle version is located on the bottom of the cab while the streetcar version is located on the top of the train.

To date, all S70s delivered in North America have had a length between 91 feet (28 m)[3] and 96 feet (29 m),[citation needed] but the 77 cars currently on order by Salt Lake City's TRAX system and the 65 cars on order for the San Diego Trolley will be only 81 feet (24.7 m) long.[4][3] The Avantos built for France have a length of 36.68 m (120.3 ft).[2][5]

While most S70 vehicles are double-ended, with operating controls at both ends, and double sided (doors on both sides), the 22 cars in service on Portland's MAX system are single-ended, with operating cabs at only one end of each car. However, they have doors on both sides, and in service they always operate in pairs, coupled back-to-back, so that each consist has operating cabs at both ends.[6]

The S70/Avanto can be configured to operate on various combinations of power supply. The Avantos ordered for France are capable of operating on 750 V DC, when running on tram or light rail tracks and on 25 kV AC, when running on main line tracks.[2]

Usage and current orders[edit]

United States[edit]

  • Houston METRORail, Texas: 18 units purchased, with delivery complete in late 2004. 19 additional units on order, procured using Utah Transit Authority (Salt Lake City) options, to be delivered starting in late 2012. The original cars are the long variant; the new cars are the shorter variant as used by UTA.[citation needed]
  • San Diego Trolley, California: 11 'full size' 92-foot (28.04 m) units purchased in first order in October 2004, with delivery complete in July 2005. A second order, for 57 81-foot (24.69 m) cars, was placed in October 2009;[7] the order was later increased to 65 'streetcar length' S70s in 2012.[4] All of the S70 vehicles are projected to be in service by 2014.[4]
  • LYNX Blue Line (CATS), Charlotte, North Carolina, United States: 16 units purchased, in service since November 2007. Four additional units purchased in 2008 and in service by March 2010 to keep up with higher than expected ridership.[8]
  • MAX, Portland, Oregon: 22 units purchased. Order for 21 cars announced on May 11, 2006;[9] later expanded by one car. Entered service starting in August 2009.[10] Order placed 2012 for another 18 cars.[11]
  • The Tide Light Rail, Norfolk, Virginia: 9 cars, ordered in 2007. First cars delivered October 2009.[12] Entered service with the opening of the Norfolk system, in 2011.
  • Utah Transit Authority, Salt Lake City: 77 units ordered; in service since August 7, 2011. The order also includes an option for 180 additional cars.[5][8]
  • Metro Transit, Twin Cities, Minnesota: 59 purchased with 40 options. Delivery began in 2012, with the first unit entering service in February 2013.[13]
  • Metropolitan Atlanta Rapid Transit Authority, Georgia: 4 cars, ordered in 2011.[14] In May 2011 Siemens announced that it had won the $17.2 million contract to build the four streetcars that run on the Downtown Loop. 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.[15] The first of the streetcars was delivered on February 17, 2014,[16] and began passenger service on December 30, 2014.[17]


An order for 22 S70 cars, placed in 2006 by Ottawa, Ontario for a planned expansion of its O-Train system, was later cancelled. Political problems had resulted in cancellation of the entire expansion project, which in turn led to lawsuits by Siemens and other contractors against the City of Ottawa.[20]
