 In June 2012 Lothian Buses expanded into East Lothian with the introduction of route 113 from Pencaitland to Edinburgh , replacing First Group 's 44B service following them withdrawing from the area . Route 113 is operated by a separate legal entity , Lothian Country Buses . Initially operated by existing Lothian buses , the service is now operated by five Wright Eclipse bodied Volvo B7RLEs and two Plaxton President bodied Dennis Trident 2s painted in a green and cream livery similar to that of the former Scottish Motor Traction / Eastern Scottish buses . In September 2014 , a second service commenced from Haddington to Edinburgh . This service is run by 5 Volvo B7RLE Wright Eclipse Urban 2 bodies buses which were formally liveried for Lothian 's " The Queen Of Scots " route 49 branding .
