Not what it seems

This is actually 'West Country' class No. 34046 'Braunton' speeding through Sandy station this morning.  However, it is currently masquerading as 'Battle of Britain' class No. 34052 'Lord Dowding' to commemorate the 75th anniversary of the Battle of Britain.  The original Lord Dowding locomotive did not survive the end of steam on British Railways and was scrapped in 1968.
