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 ??

    and Bromsgrove station has been rebuilt with a longer platform, but have the trains increased in length yet with more carriage added to them?

    I thought the advantage that electric trains have particularly at the small commuter train size is that with traction units under each carriage an infinitely long train can be coupled together, unlike a train with diesel locomotive or for that matter a steam locomotive which requires additional banking locomotives to be added.


    Bromsgrove station is at the bottom of the Lickey Incline the steepest sustained main-line railway incline in Great Britain, so the size of the trains are limited by what can get up the hill into Birmingham, which I thought was a problem that electrification can resolve.
