As sure as the moon waxes and wanes, the tides wash in and out, and the sun dawns and sets, Britain's rail fares rise every year, much to the dismay and anger of many passengers.
Sweaty and morose commuters are often packed tight into metal carriages, like tinned hot dogs, and pay thousands of pounds a year on ever-increasing fares for the briney pleasure.
Proponents of the privatisation of the UK rail network say that while there are problems, and more investment is needed, passengers have never had it so good. Surveys show satisfaction at record highs, while trains are more efficient and punctual than when state-owned under British Rail.
Critics say there is no argument for allowing private firms to siphon off profit from running a network that desperately needs as much investment and updating as it can get.
