This thread is getting tedious, your not going to get freight onto the rail in the way you lot are talking about, it just WON'T happen, there is not the capacity to run it, and you won't get new railways built just for freight, look at the costs and objections to HS2, nobody in there right mind is going to push for a new freight line.
It seems to me that the real problem is the amount of cars on the road and as has been said on here, you will not get people to give up their cars so instead people think the solution is to remove trucks/freight when in reality there just avoiding the real issue, all the problems that exist on the road network will still be there, even if you remove every truck off the road.
