HC Deb 05 July 1971 vol 820 c275W
Mr. Adley

asked the Secretary of State for the Environment what is the approximate cost per mile of renovation for use by passenger trains, of railway line from which rail services have been withdrawn on which the track remains; and what is the approximate construction cost, per mile, of urban motorway.

Mr. Peyton

Both costs vary widely with circumstances. An average figure would have little meaning.
