Network Rail runs, maintains and develops Britain’s rail infrastructure – including the tracks, signalling, bridges, tunnels, level crossings, viaducts and 17 key stations. Network Rail took over the running of the infrastructure in 2002 with the aims of improving safety, reliability and efficiency of the railway. Network Rail employs around 35,000 people and currently spends around £8 billion a year on running, maintaining and developing the infrastructure. Between 2009 and 2014 it has invested around £12 billion in enhancing the infrastructure to provide for the growth of passenger and freight traffic.
