The River Erewash is not widely known (and often wrongly pronounced – three syllables, “Er-e-wash”). Indeed, it’s an unremarkable river, meandering between its wide, low-lying valley sides, bordering Derbyshire and Nottinghamshire. It gives its name to the Erewash Canal and is the location for many of D H Lawrence’s stories, including much of the novel The Rainbow (1915).
Eastwood, the town of Lawrence’s birth, claims to be the “birthplace of the Midland Railway”, on the strength of a meeting at the Sun Inn, which led to the formation of the Midland Counties Railway in 1832.
In fact the railway didn’t reach the valley until the late 1840s, after which the local mine-owners deserted the canals to send their coal by rail to Leicestershire and London.
This was the heartland of the Midland Railway, until its rival the Great Northern Railway, egged on by local businessmen anxious to break the Midland’s monopoly, chose to compete by building a line west from Nottingham across the southern edge of the coalfield and on to Derby and beyond.
This Derbyshire & Staffordshire Extension, authorised by Parliament in 1872, spawned numerous branches to local collieries, and was intended also connect with the North Staffordshire Railway to take some of the Midland’s Burton beer traffic.
Little survives of the route, which closed in the 1960s, except for the remarkable Bennerley Viaduct, which strides across the Erewash flood-plain east of Ilkeston, opened in 1878.
The wrought-iron lattice construction, designed by the GNR engineer, Richard Johnson, was necessary because the floor of the Erewash valley was already riddled with coal workings. A brick-arch viaduct would have been vulnerable to subsidence; iron legs could be jacked up if necessary.
The structure survives because wrought iron cannot be cut by an oxy-acetylene torch, and dismantling it piece-by-piece proved unduly expensive.
It’s a unique survivor, now listed Grade II*: two taller and more spectacular viaducts, at Crumlin on the Taff Vale Railway near Caerphilly (1857, 200 feet high) and Belah near Kirkby Stephen in Cumbria (1860, 196 feet high) were demolished in 1965 and 1962 respectively.
Belah Viaduct, designed by Thomas Bouch who went on to build the first Tay Bridge, had the same lattice construction as Bennerley; Crumlin, like the surviving Meldon Viaduct near Okehampton, Devon, had distinctive Warren Trusses.
Bennerley Viaduct belongs to Sustrans, and may one day form part of the National Cycle Network. For the present, it’s remarkably difficult to approach or see. Indeed, the best view is from passing trains (on the left-hand side heading south) between Langley Mill and Nottingham.
