there are lots of companies that know how to build rail, and most use subs that can be hired by anyone rather than owning all that labour and risk themselves.

Comparing rail lines to aircraft carriers is ridiculous and discredits your entire post. If everyone inflates their price the one who inflates it the least wins. That's not how the industry actually works. its far more common to bid low and try to make up the profit in claims. You know nothing about this industry and its obvious from your writing.
