If my hon. Friend, with his long experience of railways, goes back 10 years he will recall that at the beginning of the 1980s the PSO grant was twice the present level—it was then over £1 billion and it is now £600 million—and investment was half the current level. There is a relationship, when we consider the public purse, between that which can be afforded by way of revenue subsidy and that which can be afforded by way of investment. The Government accept that for the foreseeable future regional railways will have to be subsidised. They knit together the fabric of rural Britain. I have already commented in great detail on Network SouthEast in response to an earlier question.
