The Dennis Trident 2 (the 2 standing for 2-axle) is a 2-axle

Dennis Arrow. It was built by TransBus after Dennis was incorporated into the group in 2001, then from 2004, it was built by Alexander Dennis
following the collapse of TransBus.

Design

First Kernow Plaxton President
bodied Trident 2 in 2018

Developed from the air-conditioned 3-axle

Euro III emissions standards, and could be built to 10.6 metres (35 ft) and 11.4 metres (37 ft) in length.[1] Engines were rear-mounted transversely on the right side of the chassis with the radiator mounted on the left side. This was marketed by Dennis as the 'T-drive configuration', which shortened the rear overhang and overall length of the chassis.[2]

The Trident 2 was first bodied with the Alexander ALX400 body, following on from the Alexander ALX500 on the Trident 3 chassis. Plaxton and East Lancashire Coachbuilders followed shortly after with the President and Lolyne bodies respectively. Trident 2s were intended to be compliant with statutory public service vehicle accessibility regulations introduced in the Disability Discrimination Act 1995, with an entrance step height of 325 millimetres (12.8 in) capable of being lowered to 250 millimetres (9.8 in) through a kneeling front suspension, and the 'T-drive' longitudinal system allowed for a flat floor throughout the majority of the lower deck.[2]

Operators

The first Dennis Trident 2s were delivered to Stagecoach London and Metroline in 1999, all being built with Alexander ALX400 bodies;[3][4] in 2014, London's first Trident 2, numbered TA1 and operated by Stagecoach East London, would be donated to the London Bus Museum at Brooklands.[5] A total of 2,255 Dennis Tridents would be built for London bus operators, 998 of these for Stagecoach London exclusively with Alexander ALX400 bodywork, and another 425 being built for First London with both Alexander ALX400 and Plaxton President bodywork.[6]

The Trident 2 was also initially very popular with large bus operators outside London, with a large number sold to the

Scania OmniDekka and TransBus being put into administration, sales of Trident 2 dropped significantly, leaving Stagecoach as its major buyer.[citation needed
]

In 2005, Alexander Dennis developed the new version of the Trident 2 chassis for its Enviro400 double-decker. Marketed as the Enviro400 chassis, the name "Trident 2" continued to appear on the manufacturer's plate,[10] and it retained the Cummins ISCe Euro III engine (soon replaced by Cummins ISBe 6-cylinder Euro IV) and Voith/ZF gearbox. The Enviro400 chassis also received a number of modifications such as a longer front overhang, with a different shape of fuel tank became available. Production of the older version of Trident 2 chassis continued until 2006, with the last example being delivered to Isle of Man Transport.
