THE general story of the 1500V DCEM2 express passenger electrics built for the Manchester-SheffieldWath (MSW) ‘Woodhead’ electrification scheme in the early 1950s is well known. Just seven members strong (preTOPS Nos. 27000-27006), they were declared redundant in 1968 and sold to Nederlandse Spoorwegen, the Dutch national railway operator, in 1969 where they gave excellent service until retired for a second time in 1986.
However, it could have been a very different matter had British Railways continued electrification at 1500V DC rather than switching to 25kV AC as the new standard.
Electrification of the former Great Central route over the Pennines, via Woodhead Tunnel, had been mooted for years before the first comprehensive plan was published by the LNER in 1936. Calling for nine express passenger locomotives, plus 69 for mixed traffic and 10 for banking duties, the planned 88-strong fleet would replace 181 steam engines on a more than two for one basis.
Work started on wiring in 1937, and the prototype Bo+Bo EM1 (Class 76) mixed-traffic locomotive, No. 6701, was released into traffic in February 1941. Wearing LNER apple green, it was designed by Sir Nigel Gresley and spent some time on test on the 1500V DC Manchester-Altrincham line, which had been electrified in 1931. However, with the Second World War raging, the MSW electrification was shelved and the loco went into store.
The banking locos would be rebuilt from the 10 North Eastern Railway EF1 locomotives constructed for the Shildon scheme in 1914 and 1919. Little is known about what was envisioned for the nine express passenger machines, although a proposal was made by the Swiss Locomotive & Machine Works (SLM) of Winterthur in 1939 for a 55ft-long 4-6-4 design, suggesting an arrangement similar to the NER’s EE1.

Service reductions as Covid cases increase
An increase in Covid-19 cases in early January saw the governments in Ireland and Northern Ireland impose stricter lockdown measures that impacted on public transport.
East West Rail funding go-ahead
Although it was expected, £760 million of funding has now been confirmed to build the Western Section of the East West Railway scheme.
1990s ‘N' gauge Class 950
Work on the ‘N’ gauge Class 950 Track Recording Unit project, a conversion based on a standard Graham Farish Class 150/1 model, is concluded by finishing the model in 1990s condition.
‘2024 Stock' design due soon
Cab and body mock-ups of the Piccadilly Line’s new train fleet should be released by Siemens in March.
Letting the train take the strain
Car-carrying Motorail services were an everyday feature of British Railways’ timetables from the 1950s, but were eventually killed off by the growing motorway network.
End for Harrogate line token working
Semaphores remain but, as David Russell reports, a switch to tokenless signalling on the York to Harrogate line should make it more efficient for operations.
The BSC PTA family
Brand-new ‘OO’ gauge models of the British Steel Corporation(BSC) PTA iron ore tippler wagon (and derivatives) have caused a lot of excitement in the D&E modelling community.
Graham Farish late-condition ‘Goyle'
Three late-condition (refurbished) Class 31s are part of the latest batch of six ‘N’ gauge Class 31 models to be released by Bachmann under the Graham Farish label. New toolings have been employed to create this version of the ‘Goyle’ which dates from the 1980s.
Swansong of the ‘483s'
With the Island Line’s veteran Class 483 EMUs counting down to their withdrawal on January 3, Christopher Westcott talks to two drivers who have operated the trains on London Underground and the Isle of Wight.
