I regret to inform the House that there was an inaccuracy in the answer I gave to parliamentary question 98207 on 5 March, Official Report, column 411W and subsequent comments made by the Secretary of State for Transport in debates held on 8 March, Official Report, column 1035 and 23 March, Official Report, column 1049 about how many miles of railway track were electrified between May 1997 and May 2010.
The correct answer is approximately nine route miles were electrified between May 1997 and May 2010, not 39 route miles as previously stated. This total does not include newly constructed railways.
