Dennis Trident 2

The Dennis Trident 2 is a two-axle low-floor double-decker bus chassis, unveiled by Dennis in 1997 as the replacement for the Dennis Arrow and one of the first low-floor double-deckers to enter service. Production passed to TransBus International in 2001 and to Alexander Dennis in 2004. It was developed from the three-axle Trident 3 for the United Kingdom market, with a rear engine mounted transversely on the right side in what Dennis called the T-drive layout, which shortened the rear overhang and allowed a flat floor through most of the lower deck. Early examples carried Euro II Cummins C series engines, later ones ISBe, ISCe and ISLe engines. Its first bodywork was the Alexander ALX400, and 2,255 Tridents were built for London operators. Alexander Dennis updated it into the Enviro400 in 2005.
