In the blue hour at 16.40 h, a northbound Scotrail train pulls a subtle light trail across the 2523 metre (8276 ft) long bridge over the Firth of Forth between Dalmeny and North Queensferry (about 13 kilometer west of Edinburgh). The double track bridge was built between 1882 and 1890 by Sir John Fowler and Benjamin Baker and was the longest cantilever bridge in the world at that time, as well as the longest with a span of two by 521 metres. In terms of span, the Pont de Québec surpassed it by 549 metres in 1917. The pilars are 100 meter high from the stone pedestal. For this building 54000 ton of steel was used, and 6,5 millions of rivets. The construction of the bridge resulted in an unbroken East Coast railway route from London to Aberdeen.
A continuously growing album of photos that IMHO reveal the awesome and seldom-seen beauty of the railroad world from the dimming of day to dawn's early light! From dusk to dawn, trains roll on! (I'm still finding gems of sunset-to-sunrise surprises!)
