Duple Dominant
The Duple Dominant was a design of a coach (and less commonly bus) bodywork built by Duple between 1972 and 1987. It introduced an all-steel structure and replaced the wooden-framed Duple Vega, Viceroy and Vista models.
Duple Dominant bodywork was built on different chassis types including:
front engined
mid engined
rear engined
The original Dominant had a windscreen (and matching rear windows) of the same height as the side windows. After 1976 it received a new design of grille and was known as the Dominant I. It remained in production throughout the Dominant's production life as a cheaper alternative to the Dominant II and because the deeper windscreens of the later Dominant marks were incompatible with some front-engined chassis. Some Dominant I bodies had Dominant II style rear windows, and/or headlights and front grilles. Special narrow bodies built for use on the Channel Islands retained the pre-1976 style grille until the end of production.
The Dominant II (introduced in 1976) had a deeper windscreen, rectangular headlights, a different grille and a smaller, flat, single piece rear window.
The Dominant III was designed to satisfy a Scottish Bus Group (SBG) requirement for express coaches, and featured shallow, parallelogram-shaped flat double-glazed side windows similar to those on SBG's previous Alexander M-type coaches. Most Dominant IIIs featured a small Dominant I style windscreen mounted in the lower Dominant II position so as to allow a destination display to be included without breaking the roof line, but others had full-height Dominant II type windscreens. The small high-level windows were designed for SBG's overnight Scotland to London services where quietness was more important than passenger views, but nevertheless some other operators did buy the Dominant III as a touring coach. After being retired from long-distance services many SBG Dominant IIIs were rebuilt with larger Dominant I/II or Dominant IV windows to make them more suitable for general coaching work, and many were given replacement bodies later in life.
