HS2 railway

CliveS
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 ??

    CliveS:

    ANSWER  Long distance cross country heavy transportation will ALWAYS be cheapest and quicker using diesel which is no more damaging to the environment than a hydrocarbon burning power station anyway. 




    Are you saying that long distance electric trains are actually a dead end in technology or an obsolete technology? Many countries have electrified their rail networks since 1945 but, with hindsight, was it a bad decision?


    Take into account that with diesel trains you only have the choice of hydrocarbon fuels whereas with electric trains there are more options to choose from how the electricity is generated.
