>>1645939What, Germany did the uograding conventional line to high speed line on numerous lines already, why cannot Japan copy it, other than Japan also meed regauging
Of course existing right of way won't be 100% reusable, and there will still be some speed limitation, but still better than start from scratch, and it can also have sufficient capacity to fit in non-high-speed trains around larger cities
>Hokuriku Chubu1. System compatibility is not unresolvable
2. Even if no through running, same stop interchange wpuld still be more favorable
3. It's part of the national plan
>JoetsuI mean Yamagata prefecture's Shonai area, not intended to mean City of Yamagata, sorry I wasn't being ckear enougg, although I think they could build a line connecting Sendai via Yamagata City to Niigata then to Hokuriku and West Japan
Shonai area doesn't benefit from Yamagata Shinkansen improvement
>Mini ShinkansenNah they'll be progressive improvement starting from the two tunnels and gradual removal of level crossing
>San'inConnection to Sanyo can use conventional line
>Tsuyamasame
it's not like Tsuyama is some big city
>ObamaIt just need a switch back then next stations will be Kyoto, Keihanna Science City, and Osaka
>Too slow on Hokuriku Shinkansen with TokyoThe improvements currently applying to Tohoku-Hokkaido Shinkansen can also apply to Hokuriku Shinkansen
>East KyushuI am pretty sure no matter how much engineering work is needed around Kokura station, it'll still be very significantly cheaper than tunnel/bridge connecting Kyushu to Shikoku, especially with how deep the sea is around the point the two islands are closest to each other
>SlowerWell still faster than connecting via conventional train, plus Shikoku Shinkansens being Seibi Shinkansen also mean lower default speed unless money is spent on improving it , and even then it'll still help connect Fukuoka and h4e
yy and Hiroshima
>PopulationIt applies to all routes I mentioned
