By the start of the 1950s, British Railways were making a working profit, albeit a small one. However, Britain had fallen well behind the rest of Europe in terms of dieselisation and electrification of its railways. There were political as well as practical reasons behind the resistance to dieselisation in particular: the Labour Government of Clement Attlee did not want to significantly reduce the demand for domestically-produced coal in favour of imported oil, thus both affecting the balance of payments and potentially causing unemployment. Robin Riddles, who was effectively the British Railways' Chief Mechanical Engineer, disagreed with the dieselisation programme, arguing that it would be too expensive to import oil given the large amounts of domestically available coal. He continued to order steam locomotives on a large scale and from 1948 to 1953, 1,487 steam locomotives were built.
