HC Deb 25 June 1976 vol 913 c646W
Mr. Walter Johnson

asked the Secretary of State for the Environment what is the cost in 1976 of electrifying a mile of railway track.

Mr. Marks

The cost per mile of electrifying track depends on many factors including the size of the scheme, the number of bridges and tunnels needing alteration, and fluctuating costs of component materials. In the three most recent schemes the cost per mile at 1976 prices ranged from £278,000 to £440,000
