THERE IS A FASCINATING pair of railway viaducts at Chapel Milton, near Chapel-en-Frith in the Peak District. Constructed in about 1860 and then 1890, the viaducts support a place where two railway lines diverge. The viaducts, which join each other at a bifurcation were built at different times as the dates suggest. One of the arcades consists of 13 arches and the other of 13.

Allow Wikipedia to explain:”The Midland Railway opened a new line via Chapel-en-le-Frith Central and Great Rocks Dale, linking the Manchester, Buxton, Matlock and Midland Junction Railway with the Manchester, Sheffield and Lincolnshire Railway, in 1867, giving it an express through route for the first time between Manchester and London … The eastern section, essentially a second, mirror-image viaduct in an identical style, was added in 1890 to allow trains to travel between Sheffield and the south via Buxton and the Midland’s own line.” (https://en.wikipedia.org/wiki/Chapel_Milton_Viaduct)
