Well said John.
It would be interesting to see the initial written assessment of what the project would be.On a 12 mile line there would be (I assume) the need to cross over several roads. Are you likely to get permission to make level crossings ?
And what of potential usage, are there any touristy attractions along the proposed route ?
What about planning permission ?
I feel the financial burden would be considerable before you ever got to the stage of any actual site work.
