These tri-axle vehicles have been criticised for lacking space to fit pushchairs, as well as their length causing near collisions with motorists, pedestrians and cyclists. Preserved vehicles Many vehicles previously used by Lothian Buses and its predecessors have been preserved (or are awaiting preservation) by various groups and societies. Several of the vehicles regularly appear at events, rallies and running days around Scotland and the rest of the United Kingdom. Route branding Route branding been used by Lothian since the introduction of low floor vehicles, although many liveries have now been phased out in favour of more uniform branding. In 2010, the Harlequin livery used to identify low floor buses began to be phased out due to the company achieving full low-floor operation, with the company returning to their traditional madder and white livery. In July 2011, Lothian Buses introduced 60 new double deck buses. These buses continued with the same madder red and white pattern on the outside of the bus but Lothian Buses changed the seats to a matching madder red colour. They also changed the entrance to the bus to a more wooden effect. Routes 4, 5, 19, 23 and 27 were the first buses to receive this branding.
