The Ultra Low Floor tram (ULF) is a low-floor tram operating in Vienna, Austria, and Oradea, Romania, built by a consortium composed of Siemens and ELIN in Vienna. It has the lowest floor-height of any such vehicle.
OverviewEdit
In contrast to other low-floor trams, the floor in the interior of ULF is at sidewalk height (about Template:Convert above the road surface), which makes access to trams easy for passengers in wheelchairs or with baby carriages. This configuration required a new undercarriage. The axles had to be replaced by a complex electronic steering of the traction motors. Auxiliary devices are installed largely under the car's roof.
The ULF technology went into testing in the early 1990s. Since 1998, ULFs have been in use on Vienna's tram network. As of mid-2008, 302 cars were in operation (150 cars since mid-2006, and another 152 as of 2007).
Siemens ULF trams were introduced in Oradea, Romania, on 24 April 2008, and are the only ULF trams outside Austria.<ref>Template:Cite news</ref>
