High-speed rail Stress Situation

High-speed rail Stress SituationAug 27, 2021"By many measures, the U.S. freight rail system is the safest, most efficient and cost effective in the world." Federal Railroad Administration, October, 2009. I'm just your average, everyday, uncivilized howling "anti government" critic of mass government expenditures for "High Speed Rail" in the US. And I'm gosh darn proud of that.
