It's low hanging fruit in that everything involved is well understood with very seasoned technology and a deep amount of suppliers and engineering knowledge. As I said, we were doing this stuff in the 19th century, and have kept doing it (in some countries, just not NA). This sort of solution doesn't require any sort of technological breakthroughs, or technologies that do not exist. Trying to solve climate change based on working on new technologies that don't currently exist and may not ever exist seems harder to me, and yet remarkably we see people pointing to this approach instead of well understood solutions we already have. Accordingly I'd call implementing proven technology relatively easy. One could get started on it tomorrow.

You can say the same for solar panels and/or batteries? After all, they exist right now and can be mass produced. Moreover the electricity grid actually accounts for a significant chunk of global emissions, unlike aviation. The only thing really stopping them is cost, but then that's basically the same issue that HSR has, which is cost/delays/political issues. >As I said, we were doing this stuff in the 19th century, and have kept doing it (in some countries, just not NA). "[trains] in the 19th century" aren't a serious competitor to airplanes in the same way that ocean liners aren't a serious competitor to airplanes.
