Question to the Department for Transport:

To ask the Secretary of State for Transport, what the average savings in travel time were from each rail electrification project in England and Wales in each of the last 10 years.

No time has been saved by the electrification alone. Some of the routes have had major route upgrades, including line speed improvements, which has benefitted diesel trains as well as electric ones.

The core purpose of electrification is not normally for speed Examples of this are between London and Edinburgh, where diesel and electric trains are scheduled in the same journey time.
