We would all agree that an express link fro London to Birmingham and Manchester would be of great benefit BUT do we have to electrify the entire length of track or just the parts inside city boundaries.
We can half the construction/infrastructure cost if we use diesel electric trains cross country and convert to electric only inside the city.
This is environmentally friendly as power stations are only 60% efficient at best and mostly use gas at normal/peak times anyway; isn't it ??
