Diesel traction was pioneered in Britain by the LMSR in the 1930s, with a variety of shunting locomotive types, and by the late 1940s steps had been taken towards the arrival of the first diesel locomotive intended for main line work. Under the guidance of the LMSR’s C.M.E., H.G.Ivatt, and the co-operation of English Electric Ltd.,1600hp diesel-electric No.10.000 took to the rails in December 1947.
Here was the first of an entirely new breed – the 16-cylinder English Electric diesel engine operating a generator, supplying power to the six electric motors driving the road wheels of the two bogies. English Electric had long been involved with non-steam design and build, mostly for overseas railways, and were at the forefront of most development and innovation around the world.
The use of traction motor/gear drives had already replaced the jackshaft/side rod drives of the pioneer shunters, but No.10,000 was its ultimate development on the LMS. Diesel power was also the first step towards the elimination of steam locomotives as the principal source of main line motive power. But nobody looked at it that way then; it was the train of the future, something for small boys to marvel at on station platforms.
These first main line diesel types were perhaps considered along the lines of proposed ‘atomic trains’, a far-off concept in the post-war era. Strangely enough, by the time BR came to embark on its dieselisation programme, diesel locomotives had become smelly tin boxes on wheels, and the seeds of steam nostalgia were sown. It’s doubtful that steam era footplatemen were anything other than happy with improved conditions.
So much for the train of the future!

The Southern Railway too was progressing with main line diesel traction in the post-war era, but it was not to be for a further three years after nationalisation that their locomotive appeared. Meanwhile the GWR had decided as usual to pursue an independent course, with plans for gas turbine types, although these too would not be completed until 1950.
This cartoon appeared in the April 1948 issue of the railway’s “Carry On” magazine, and reflected the new technology, and its need for heavy fuel oil to power the locomotive, and not coal.
