Calgary Transit operates a light rail service using these Siemens-Düwag U2 2-car 6-axle articulated units which run on standard gauge drawing 600 volts DC from the overhead. The outer trucks have both axles powered and the centre truck (under the gangway) are non-powered. These high floor units require platforms for loading and unloading. Part of the system operates along roadways and some is on a private right-of-way.

Unit 2228, from the 2003 batch, heads along 7th Avenue at 8th Street on Friday May 20th, 2005. This view illustrates the staggered high-level platforms.
