How Green is my Valley
The unique two-tone green liveried 'identity crisis' Freightliner Heavyhaul class 66 No.66522 crosses Ribblehead Viaduct in charge of the 4S11 Drax Power Station to Killoch Colliery coal empties. The magnificence of the viaduct naturally encourages compositions to encompass the full structure, but equally I think that its lofty height is emphasised in just a small portion of the structure being included in the frame. 440 yards long with 24 arches, Ribblehead viaduct was built between 1870 and 1875. All the piers are 6 feet thick except for every sixth pier which is built 18 feet thick as a safety measure in case the viaduct collapsed like a row of dominoes. Built of locally quarried limesone, it is also known as Batty Moss Viaduct. The height is 104 feet from the top of the parapet wall to the ground at span number 20.
