The Siemens S70 or Avanto is a low-floor light-rail vehicle (LRV) or streetcar manufactured by Siemens Mobility, a division of Siemens AG.

The S70 is in use, or on order, by several light rail systems in the United States, where Siemens refers to this model only as the S70.[1] In this field, it competes mainly with Bombardier and Kinki Sharyo low-floor LRVs and modern streetcars manufactured by Inekon and Brookville Equipment Corporation.

In Europe, Siemens's Combino and Avenio models are the preferred offerings for purely light rail or tramway systems; and the same S70 model, under the name Avanto, is principally sold to tram-train systems which, in whole or part, share their tracks with heavy rail trains. In the tram-train market, its principal competitors are Bombardier’s Flexity Link tram-train and Alstom’s Regio-Citadis and Citadis-Dualis tram-train variants. To date, the Avanto has been sold to two tram-train operations in France.[2]


Size and configuration

The S70/Avanto has 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 streetcar version is 9 feet (2,743 mm) shorter than the standard LRV version. There are some interior differences as well: the LRV version has the upper seats facing the cab, while the streetcar version has the upper seats facing the doors of the train. In addition, the horn on the LRV version is located on the bottom of the cab while the streetcar version is located on the top of the train.

Earlier S70s delivered in North America had a length between 91 feet (27.74 m)[3] and 96 feet (29.26 m),[4] but the 77 cars used by Utah Transit Authority for the Salt Lake City-area TRAX system and the 65 4000 series cars on the San Diego Trolley will be only 81 feet (24.69 m) long.[3][5] The SD Trolley vehicles are also designed to operate in tandem with older Siemens SD-100 vehicles, with a SD-100 sandwiched between two S70 vehicles. The Avantos built for France have a length of 36.68 m (120 ft 4 18 in).[2][6]

Most S70 vehicles are double-ended, with operating controls at both ends and doors on both sides. An exception is the 40 cars in service on Portland, Oregon's MAX system, which are single-ended and have cabs at only one end of each car. However, in service they always operate in pairs, coupled back-to-back, so that each consist has operating cabs at both ends.[7]

The S70/Avanto can be configured to operate on various overhead power supply systems. 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 25 kV AC when running on main line tracks. The vehicles operating in Paris currently operate on AC only; its DC capabilities will not be used until an extension of the current line to Montfermeil is completed.[2]
