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, 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.
Size and configuration
The S70/Avanto has a modular design, and can be built in a number of different sizes and configurations.
To date, all S70s delivered in North America have had a length between 91 feet (28 m) and 96 feet (29 m), but the 77 cars currently on order by Salt Lake City's TRAX system and the 57 cars on order for the San Diego Trolley will be only 81 feet (24.69 m) long. The Avantos built for France have a length of 36.68 m (120.3 ft).
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.
The S70/Avanto can be configured to operated off various combinations of power supply. The Avantos ordered for France are capable of operating off 750 V DC, when running on tram or light rail tracks, and off 25 kV AC, when running on main line tracks.
