This 3D model was originally created with Sketchup 7 and then converted to all other 3D formats.

In contrast to regular low-floor trams, the floor in the interior of ULF is low enough to be at the same height as a sidewalk (about 18 cm or 7 inches above the road surface), which makes access to trams particularly easy for passengers in wheelchairs or with baby carriages. This configuration required a completely new design of the undercarriage, and the axles had to be replaced by a complicated electronic steering of the traction motors. Auxiliary devices are installed largely under the car’s roof.
