Is high-speed rail more environmentally friendly?

HSR reduces traffic congestion and gaseous waste emissions, as well as environmental pollution, by replacing traditional transportation (Anderson, 2014). According to the study of Chen et al. (2016), HSR has a significant and positive effect on environmental degradation.

While the US was a passenger train pioneer in the 19th century, after WWII, railways began to decline. The auto industry was booming, and Americans bought cars and houses in suburbs without rail connections. Highways (as well as aviation) became the focus of infrastructure spending, at the expense of rail.
