If the transport companies don’t require electric vehicles the infrastructure company won’t builds it. I don’t say that’s the case but it could be. If everybody has only a bicycle you don’t spend money on a highway.
That makes no sense. The government owns the railway, not the companies. They are the ones struggling to put in electric lines.
Also battery electric trains are a big step up from diesel. I don’t get why you are complaining.
My bad. I was going to rant about the relation between train companies having to change the trains.
But I just remembered who is “governing” UK.
