The Bombardier CR4000 is a 76% low floor model of the Bombardier Flexity Swift trams operated by Tramlink in London. They are based on and very similar in appearance to the K4000 used on the low-platform routes of the Cologne Stadtbahn network. Built between 1998 and 2000, the trams entered service in the spring of 2000.
