High Quality Content by WIKIPEDIA articles! The Scania OmniDekka (introduced in 2003 as the East Lancs OmniDekka, sold as the Darwen OmniDekka between 2007 and 2008, and then sold as the Optare OmniDekka between 2009 and 2011) is a double-decker bus built for sale in the UK. The model is based on Scania N94UD (with newer examples based on Scania N230UD/N270UD) chassis, with a body by East Lancashire Coachbuilders, based on similar bodies mounted on Alexander Dennis, VDL and Volvo chassis but with a modified front, similar to the OmniCity which instantly makes the bus recognisable as a Scania product.
