I will be brief: it’s a bonkers idea.
Well history is littered with successes that were bonkers ideas. From an engineering perspective, the person that built the Florida Keys Overseas Railroad was thought to be certifiably insane but the task was accomplished. I suppose it did get partially destroyed during a very strong and almost unprecedented hurricane but the point still stands.
Well I certainly admire tenacity … though you pick an unusual example of a “success” … wasn’t the railway company already bankrupt at the time much of the Overseas Railroad was destroyed by the hurricane you mention? Perhaps a not wholly encouraging comparison to draw?
