In 1994 and 1995, British Rail was split into infrastructure, maintenance, rolling stock, passenger and freight companies, which were privatised from 1996 to 1997. The privatisation has delivered very mixed results, with healthy passenger growth, mass refurbishment of infrastructure, investment in new rolling stock, and safety improvements being offset by concerns over network capacity and the overall cost to the taxpayer, which has increased due to growth in passenger numbers. It has also led to some confusion as to who looks after different aspects of the rail service among the general public. This is because, for example, different companies run the tracks to those that run the trains and locomotives. Since privatisation, passenger levels have more than doubled and have surpassed the level they had been at in the late 1940s. But while the price of anytime and off-peak tickets has increased, the price of Advance tickets has dramatically decreased in real terms: the average Advance ticket in 1995 cost £9.14 (in 2014 prices) compared to £5.17 in 2014. Subsidies to the rail industry have slightly increased from £3.7bn in 1992–93 to £3.9bn in 2012–13 (in 2013 prices) but more than halved in terms of subsidy per journey from £4.98 to £2.46.
