British rail services are often held up as an example of how privatisation doesn’t work. In fact, it proves the exact opposite: the parts of the railway that were genuinely exposed to market incentives have performed much better than the parts that remained under detailed government control. British rail provides something as rare as an independent variable experiment in economics: in the early 1990s, two comparable sectors exited full state ownership but followed very different models. The "privatisation" of the British passenger rail industry was never actual privatisation. It was a transfer of legal ownership, but not of control or of full economic interest, to the private sector. Private Train Operating Companies (TOCs) were awarded heavily regulated, fixed-term franchises which gave them monopolies over their specific routes. The state continued to dictate operations and investment obligations, assume revenue risks, specify timetables and set fares, while private entities extracted strictly regulated profits. Contrast that with the rail freight sector, which was structured to be an open and competitive private market with operators taking full financial risk. Freight operates under pure open access model where any licensed private company can buy track space from the infrastructure provider and compete on any route. This lack of franchise protection has paved the way for many new private entrants over the decades. Unlike the much criticized passenger rail sector, the privatisation of rail freight has been an unmitigated success. It spurred massive private capital investment in rolling stock and reversed a decades-long decline in freight volumes. Costs have dropped as productivity has improved significantly, with rail freight now carrying 70% more goods but with 30% fewer train paths than under state control. The British rail sector tells a story of private success versus the mess of the hybrid passenger model that never was actual privatisation, but government granted monopolies to heavily regulated and subsidised franchises. Actual privatisation means not only transfer of ownership, but of control and full financial risk to the private sector. The British rail freight sector shows what can actually be achieved by proper exposure to the dynamic forces of free market incentives.
