"On the Great Western Main Line, there is a case for electrification of the route from London Paddington through to Oxford and either to Bristol or Swansea depending upon service patterns."
"On the Midland Main Line, there is a case for electrification of the route from Bedford to Nottingham and to Sheffield (London St Pancras to Bedford already being electrified)."
The report calls for feasibility studies to be conducted.
