Panic not everybody !
The Strategic Rail Authority is going to be scrapped. This was one of the announcements in the Government White Paper "The Future of Rail" which came out in the summer. Rail planning functions (like this sort of decision) are being transferred to the Department for Transport.
So they're going out with a bang and some gross nonsenses, although not as big as some they have pulled previously (such as wrecking the London to Manchester train service which has given such a gift to the airlines on that route - ask VLM where their London City to Manchester passengers have transferred from).
But BAA, BA at Gatwick, and the existing operator of Gatwick Express, are adept at lobbying politicians to avoid such hare-brained schemes. And I am sure they will. The untruths and partial statements that the SRA came up with for the Times article are very easily rebuffed.
Incidentally, it is said that when the trains were privatised, anyone with any commercial ability went to the train operating companies like Gatwick Express. The technically able staff went to Railtrack, where they floundered in the new privatised world until it went bust on them, while the British Rail plonkers left over got stuck with the SRA and its ilk.
