new subsidiary named Lothian Motorcoaches that commenced with five Plaxton Panther bodied Volvo B11Rs and three-second-hand Van Hool bodied Volvo B12MTs. A new depot is being built for Lothian Country and Lothian Motorcoaches in the Newbridge area. The design of the livery used by Lothian Motorcoaches was not related to the other brands of the group, being entirely dark grey with silver lettering, although the Airlink service is now operated with dark-blue Enviro400 XLBs, in a font similar to the Motorcoaches brand. Night buses Lothian Buses also operates a nightbus network. Ridership increased when the routes were re-numbered and re-routed to match daytime routes and increased in frequency. The operation of night buses provides a continuous 24-hour bus service to some areas of the city. This ticket allows for unlimited travel all night on any night bus. From 5 November 2016, East Coast Buses introduced its own nightbus service under the NightHawk brand, to North Berwick and Dunbar. In December 2018, Lothian Country introduced the Nightbus N28 to Livingston. Infrastructure and operation The previous company headquarters and engineering works in Shrub Hill, off Leith Walk, were sold in 1999 subject to planning permission, after being occupied by the company since 1871. After repeated delays, controversies and a public inquiry, in 2004, the site was sold to BL Developments for £12 million so that the site could be developed flats and houses. The company as a whole operates three travel shops, six depots (Annandale Street, Longstone and Marine in Edinburgh and North Berwick and Musselburgh in East Lothian) and Livingston in West Lothian. There is also a driver training school and an engineering depot at Seafield. Edinburgh has a network of park & ride services operates by Lothian Buses, with sites located at Hermiston, Ingliston, Sheriffhall, Straiton and Wallyford. Lothian's double decker buses were unique in Scotland in displaying the destination at both the front and rear. In early mornings and late evenings, some services are curtailed to the city centre or to early termini, in the transition to the night bus service. In such cases, 'Part Route' is displayed in the intermediate display. Certain routes have all day short working termini, and minor diversions which are often indicated through the use of internal or external 'tram boards'. Since 2006 double-deck deliveries feature a 'Route Diverted; intermediate display, used when road closures cause a service to be diverted from its normal
