The three-sectional single-direction eight-axles low-floor motor tramcar VarioLF3

The one-way run vehicle is designed for urban transport and high way lines. It consists of three sections carried by four bogies. The sections are hinged and joints are mounted over center bogies. Height of car floor is sectional i.e. 860/350 mm. Individual sections between bogies have a lower floor, 350 mm above the top of the rail.

Trave­lling
