Set 800 104 was chosen for the launch of the flagship 05.40 Flying Scotsman service from Edinburgh to London King's Cross on August 1 2019, along with the 17.30 return working, and for the occasion a new livery 'Celebrating Scotland' was designed, featuring a newly created LNER tartan. Designed by Ken MacDonald, of Houston Kiltmakers in Paisley, the tartan colours combine blue for Scotland, red for England, white for the Yorkshire rose, purple for the heather of Scotland, green for the rolling hills and landscape along the ECML and silver grey to represent the tracks of the railway.
