Is not one of the proposals for the Thames gateway the extension of the valuable North London link line from Silvertown across the river to Woolwich arsenal and along the North Kent line to the area of the hon. Member for Dartford (Mr. Dunn)? Is the Minister aware that the Government insist that that should be funded by the PFI? The revenue from about a mile and a half of track will certainly not pay for the capital, so they are effectively blocking an imaginative and sound public proposal.
