London to Glasgow in five minutes

The £9bn modernisation of the UK's West Coast mainline, linking London and Glasgow, has been completed.
Network Rail says services will be improved and journey times cut by up to 30%, but not quite as fast as in this video clip.
With the help of a footage which has been speeded up, watch the journey from London to Glasgow in just five minutes.
For technical reasons a short stretch near Milton Keynes is missing from this video.
