Rail racket

First the congestion charge at £5 then £8, then the tube ticket is pushed to £3 (making LU the most expensive tube in the world) and now we learn this:
Rail fares will treble as cheap tickets go (Times, 20/01/06)

Is it the best way to encourage commuters to use environment friendly alternatives? While aviation fuel is not taxed?

This is nothing more than racketting people whose only crime is to go to work every day!
