This policy was overtaken by political and economic events. BR's financial position was worsening as costs rose and traffic and revenue declined. BR's accounts had shown an overall negative balance since 1954 (−£23 million then, worsening to −£62 million by 1956) and in 1956 the organisation's net revenue fell into the negative for the first time: a loss of £16.5 million. Costs were still climbing, market share and volumes of both passenger and freight traffic were falling rapidly, and BR was facing a perpetual manpower shortage as the high employment and rising working and living standards and wages throughout the economy in the 1950s made working on the railways – especially the dirty, labour-intensive steam locomotives – unattractive. The railways were still suffering from a general public image of being outdated, inefficient and run down.
