English: Down coal train emerging from Woodhead Tunnel.

View eastward, through the tunnels towards Penistone, Barnsley, Wath Yard, Sheffield etc.; ex-GC Manchester - Sheffield main line. Although over four years are to pass before it is opened, work is already well under way on the New Woodhead Tunnel (on the right); the pilot tunnel is being bored and a new bridge begun over the River Etherow in the foreground. The locomotive is a Thmpson Class O1 rebuild (8/46) of ex-GC Class O4 2-8-0 No. 63886.
Woodhead Tunnel and Sheffield (Victoria) - Manchester railway
Shortly before World War Two, a start was made on the electrification of the LNER main line between Rotherwood Sidings (east of Sheffield Victoria) and from Wath Central via the Worsborough Branch to Penistone and over the Woodhead route to Manchester London Road and other points off the main line including Glossop. The war interrupted the electrification for over 10 years, although the steel standards for the overhead catenary bordered the route over the intervening period.

After the war it was found that the two 3-mile single-line Woodhead Tunnels (now almost 100 years old and traversed latterly by 100 steam trains a day) were almost collapsing and beyond economic repair. Therefore before the electrification could be completed a new much larger double-track tunnel would have to be built, parallel to and on the south side of the old bores. Work began in August 1949 and was completed, along with the electrification (also new stations at Dunford Bridge and Woodhead and a new bridge over the River Etherow at Woodhead) in June 1954. However, the pre-war scheme to electrify the railways through to Manchester Central, the Docks and the Trafford Park industrial area had been abandoned, 'Motorway Madness' ensued, the M62 was built instead and the whole modernised railway was closed down and ripped up (between Hadfield and Penistone) in July 1981!

My brother-in-law, Andrew Sharman, was Chief Site Engineer for the Consultants, Sir William Halcrow & Partners, for the New Woodhead Tunnel (also the Thurgoland Tunnel near Sheffield). He and his family were provided with a bungalow at the Dunford Bridge temporary workers' camp, so I used to visit and was taken all over (and into) the construction works, and took photographs. (See e.g. SK1199, SE1502, SE1602. For a detailed description of the the whole project, see E.M. Johnson, 'Woodhead: the Electric Railway', Foxline, Stockport 2001: ISBN 870119 81 9).
