Tatra T6B5 is a Czechoslovak-built high floor four axle tram with a pulse-width-modulation ('chopper') speed control.

This model of tram was produced by CKD Praha in Smíchov, Prague in the period of 1983–1995, following one year in Zličín until 1996.

Its most noticeable difference is its extra width, which causes the front end not to look as "pointed" as the other T6 types.

Tram cars can be used autonomously as well as in multiple units, controlled from a single console.

1,279 trams were produced and delivered to:[1] Note: This is the list of first owners.
