Any large infrastructure project isn't going to be done by a single private organization. It is way too big of a gamble, it has to be funded and overseen by the United States government. The only reason a transcontinental railway was built in the U.S was because of government subsidies. These subsidies were competed over by Union Pacific and Central Pacific, whoever built the most rail first got the most land grants and cash. You could argue that the quality was low because of the initiative but it was iterated on and improved over time.
