The 1L05 Swansea - London (Paddington) First Great Western High Speed Train (HST 125) crosses Porthkerry Viaduct in the Vale of Glamorgan, with a view of the Bristol Channel and Somerset coast in the background. High speed passenger trains use the South Wales main line between Cardiff and Bridgend but occasionally are diverted along the Vale of Glamorgan line which follows the coast from Llantwit Major to Barry. I thought it worth getting up early to catch the shot, which was taken at 04:54 as the sun started rising.
A growing album of photos that IMHO reveal the awesome and seldom seen beauty of railroads in the dimming of day to dawn's early light! From dusk to dawn, lights are on! (I still find new "Lights In The Night"!)
