Train fares - Unfair.
The railways of Britain are the backbone of the transport industry. With the rising fuel prices, rail transport is becoming far more appealing as a means of getting places, yet rail fares are constantly mounting. A reduction in train fares would incentivise the public to use this valuable utility, therefore reducing congestion on the roads, reducing national C02 emissions as well as motoring accidents.
I'd also argue that I don't see the point of peak fares. At a time when people are trying to be encouraged to use trains instead of cars to work, why is it more expensive to travel at peak times? Fares should be the same all times of the day. Otherwise you discourage people from using trains and its not as if people are paying for a better service at peak anyway.
If more trains were added to our network, frequency increased and fares were drastically cut it would encourage many more people to use them and cut road traffic. The same can be said for buses !
