tram works, George Street for pedestrianisation and Leith Street for the reconstruction of the St James Centre. The majority of current routes pass through the city centre from opposing termini, either crossing or following Princes Street in full or in part. This means that there are some arteries in and out of the New Town that are served by as many as a dozen different routes, such as Nicolson Street and Leith Walk. Some of these services, like services 3, 26 and 37, extend into outlying towns in East and Midlothian. There are also some more orbital routes, such as service 38. Liveries Traditionally, Edinburgh Corporation, LRT and Lothian Buses had been generally painted in a madder (a dark red) and cream (or white) livery. When low floor disabled access vehicles were introduced in the late 1990s, they were given their own distinguishing "harlequin" livery, moquette covered seating and brightly coloured floors and walls. The last high step bus was removed from service by Lothian in the late 2000s, making the distinction irrelevant. Lothian began to phase out the harlequin livery in May 2010, replacing it with a version of the traditional madder and white colour scheme. This had sweeping curved lines, having been updated to suit the body shapes of more modern buses. The last harlequin bus was repainted in 2016. In late 2016 a new livery, known as the fleet of the future livery, was unveiled on a batch of new Wright Gemini 3 Streetdeck style buses, for route 22. The angular shape and style of this livery was a complete departure from anything Lothian had designed before, and as of 2021 is the standard livery for all new vehicles. The livery underwent a minor adjustment when a fleet of new Alexander Dennis Enviro400 XLBs were put into service in 2019, with smoother curves and a lack of a smaller 'cheatline' on the bus's lower sides. While the Enviro400 XLBs carried the coat of arms of the city of Edinburgh on each side, every batch of vehicles bought thereafter have not had the same coat of arms added. Airlink and Skylink Lothian directly operates three services to Edinburgh Airport; Airlink 100, Skylink 200 and Skylink 400. This is in addition to the service provided by Edinburgh Trams, which has one of its termini at the airport. All Lothian airport services use special airport fare zones, meaning a single
