Template:High-speed railway lines
From Infogalactic: the planetary knowledge core
PLEASE MIND
Only built HSR dedicated lines in commercial service. No under construction, no proposals, no visions, no fantasies.
And no conventional lines with speedy services, like Russia's Moscow - Saint Petersburg
(Qinhuangdao-Shenyang, Hefei-Nanjing, etc count as high-speed lines with conventional services)
