Dinting Viaduct is a 19th-century railway viaduct in Glossopdale in Derbyshire, England, and carries the Glossop Line over a valley at the village of Dinting. It crosses the Glossop Brook river and the A57 road between Manchester and Sheffield. First opened in 1844 as part of the original Woodhead Line, the viaduct has been modified a number of times, most notably the addition of seven brick strengthening piers in 1918–20. The viaduct comprises three sections: starting from the south end, there is a series of seven stone arches, each wide. The central section consists of five openings (later divided by strengthening piers). A further four stone arches take the railway to the northerly junction with the Hadfield branch and into Dinting station. It is of similar design to the shorter Broadbottom Viaduct〔 about down the same line, which crosses the River Etherow at Broadbottom. ==History== The modern-day Glossop branch line originally opened as the Woodhead Line in December 1845, which linked Sheffield to Manchester. It was closed in 1981 leaving only the Manchester to Glossop/Hadfield section still in operation. The viaduct over the River Etherow at Broadbottom had been completed in December 1842, extending train services to Glossop, with the contract for the Dinting viaduct being let in June that year. In August 1844 the bridge was opened allowing trains to reach Hadfield from Manchester. The original construction of the two bridges used laminated timber arches.〔 By 1856, the level of rail traffic and the weight of the trains had increased so much that the existing timber viaducts were considered inadequate, and in 1859 wrought-iron girders were installed to replace the timber arches. By early the following year, this work had been completed on both bridges. Over the next 60 years, the level of traffic increased yet further, partly due to the heightened use of coal trains, so that the 1859 works became insufficient to deal with the weight. Seven brick strengthening piers were inserted during the years 1918–20,〔 and again at Broadbottom, leaving the irregular pattern of piers seen today.〔 The last major work carried out occurred in the 1950s in preparation for the electrification of the line.〔(【引用サイトリンク】url=http://glossoptours.blogspot.co.uk/2012/03/dinting-arches.html )〕 The first electric train travelled over in 1954.〔(【引用サイトリンク】url=http://www.topforge.co.uk/Photographs/Woodhead.htm )〕〔 In 2012–13, an extensive refurbishment was undertaken by Network Rail, the viaduct's maintainer, including strengthening the girders, installing new bearings and repairs to the steel, brickwork and masonry. It was also repainted olive green. The scheme cost £6.4 million. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Dinting Viaduct」の詳細全文を読む スポンサード リンク
