Sadly these fare rises are not going away any time soon, in fact the rises will probably increase well above inflation and the RPI over the next few years. Especially now that TfL are trying to fill the black hole left by the partial collapse of the government's ill thought out PPP experiment - thanks Gordon!
I would also guess that TfL will start squeezing the remaining privateering firm (Tube Lines) to go the same way as the failed one (Metronet). It may be expensive but having one company run the trains and a seperate company look after the infrastructure simply does not work. The Jubilee line fisaco being a prime example!
As much as I hate the guy, Livingstone (and every other 'expert' who reviewed it) was right in their damning of PPP experiment!
