Airport. 50 Omnicities were also ordered in 2003 for service in Amiens, while fleets of OmniCities were sold to operators in Angers and Calais. OmniCities were sold to Italian operators in Milan, Genoa, Bergamo and Venice, while in Spain, Valencian operator EMT purchased a total of 81 rigid Omnicities from 2000 to 2004. United Kingdom Single-decker The single-decker OmniCity was first introduced in 2002 in right-hand drive for the United Kingdom market. The earlier version of the single-decker OmniCity was known as the CN94UB. The Euro IV version was known as the CN230UB or CN270UB, the 230 and 270 indicate the maximum power (in hp) of the engine. The Scania OmniCity single-decker has a rounded roof dome with a single-curvature windscreen and a separate destination display. Unlike the Scania L94UB and OmniLink, the OmniCity features a full low floor without the need for steps or ramps to reach the rear seats, similar to the Volvo B7L. The Go-Ahead Group were the most popular customer of the rigid single-decker OmniCity, purchasing a total of 132 of the type, seventy of these going to Metrobus of Crawley for both its London and south-east England operations. Additional operators of rigid single-decker OmniCities included 78 with Menzies Aviation, 42 with the FirstGroup, 48 with both Arriva UK Bus and Nottingham City Transport, and 24 with Cardiff Bus. Newport Bus, a popular operator of Scania buses, purchased 38 single-deckers throughout the OmniCity's UK production run, buying no more Scania products after production ended in 2011. Double-decker In 2005, Scania announced the introduction of the OmniCity 2-axle double-decker bus to complement its OmniDekka double-decker bus sold in the UK. It has a full low floor and is a complete Scania product, unlike the OmniDekka which features a body by East Lancashire Coachbuilders. The early 2-axle double-decker OmniCity uses the N94UD chassis, the same as the OmniDekka. A demonstrator was delivered to Travel West Midlands (now National Express West Midlands) and entered service in November 2005; orders for five more OmniCities subsequently followed. The first order was for five buses by Lothian Buses of Edinburgh which entered service during the summer of 2006 on the 'Airlink' express network. Lothian Buses subsequently ordered a further 10 buses to replace the Dennis Tridents on the network; these buses entered service in late 2007. Initially, the OmniCity double-decker was in limited production, until the Euro IV version was launched. The
