All Network Rail railways: £4479M / 20,000 miles of track = £140000/km Strategic Road Network: £700M / 4,436 miles = £98000/km Not included: cost of pollution

All Network Rail railways: £4479M / 20,000 miles of track = £140000/km Strategic Road Network: £700M / 4,436 miles = £98000/km Not included: cost of pollution, injuries and deaths on the roads. Not considered: potential and actual capacity of the roads vs the railways, potential for historic underinvestment meaning higher current costs, whether these statistics mean a single track/road lane or all the tracks/lanes, usage costs for passengers and freight. A breakdown of the railways costs would be useful for a better comparison, i.e. major lines only. https://www.networkrail.co.uk/wp-content/uploads/2021/07/Annual-report-and-accounts-2021.pdf https://www.networkrail.co.uk/wp-content/uploads/2021/07/Ann... https://assets.publishing.service.gov.uk/government/uploads/system/uploads/attachment_data/file/448276/strategic-road-network-statistics.pdf https://assets.publishing.service.gov.uk/government/uploads/...
