§ 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
