These vehicles have since moved onto Skylink, still with the light blue livery. other Skylink services use a medium blue and white version of the angular livery. From August 2019, Enviro400 XLBs have been introduced on the Airlink Service, with a dark blue plain livery with a large gold Airlink logo on both sides. East Coast Buses In summer 2012, First Scotland East withdrew route 44B from Edinburgh to Pencaitland. This prompted Lothian Buses to expand into East Lothian much further than they had for years; far past the Tranent terminus of the service 26. Operations were initially branded as East Lothian Buses, and service 113 launched on 12 June 2012. A second service was added in September 2014 (the 104 to Haddington). The brand name was changed to Lothian Country Buses. One reason for launching as a separate brand was to make it easier to introduce a zonal fare system, rather than the flat fare of Lothian Buses. First Scotland East announced in June 2016 that they would be withdrawing entirely from East Lothian by 14 August, believing the county to be unprofitable. Lothian later announced the creation of a wholly owned subsidiary company, East Coast Buses, to again fill the gap left by First. The new company also took over the former First depots at North Berwick and Musselburgh, and took on many former First staff. From 23 April 2017, the two Lothian Country Buses routes were integrated into East Coast Buses. Liveries and vehicles East Lothian Buses services were initially operated by existing Lothian vehicles. The service was later operated by five Wright Eclipse bodied Volvo B7RLEs and two Plaxton President bodied Dennis Trident 2s. The East Lothian Buses/Lothian Country Buses livery was a version of the standard Lothian design featuring sweeping curved lines in bright green and cream, similar to the livery of the former Scottish Motor Traction/Eastern Scottish buses. East Coast Buses uses a version of the more recent, angular Lothian design, in green and grey (though the ECB green is slightly bluer than that formerly used by LCB). Lothian Country In June 2017, a new subsidiary named Lothian Country commenced operating route 43 to South Queensferry after the previous operator Stagecoach East Scotland deemed the service not economically viable. This new operation re-used the recently defunct Lothian Country Buses brand, for unrelated services travelling the opposite direction out of the city. On 19 August
