铁路以直流1500V电气化为主的国家,也只有日本法国荷兰而已
在欧洲有直流电气化铁路的国家,主流是直流3000V(比利时/西班牙/意大利/波兰/捷克斯洛
伐克/俄罗斯等)
英国本来要在1920年代也学邻国法国荷兰那样的直流1500V铁路电气化,最后却因为种种原
因没做,反而是战后的电气化以交流25KV50HZ为主
(不过我认为,英国南部那一批还在用直流750V+第三轨的一般铁路路线,可以转成1500V直流
化+架空线化)

After World War I, the UK Government set up a committee to investigate the
various systems of railway electrification; in 1921, it recommended that
1,500 V DC overhead should be the future national standard.[4] Several
schemes were implemented in its wake, but the Great Depression and World War
II meant that very little work was done. Technological advances after 1945
meant that the 25 kV AC system was adopted instead for the West Coast Main
line and Glasgow suburban electrification (as set out in the BR 1955
Modernisation Plan). However, at the same time, large amounts of money had
been (and were still being) spent converting several lines to 1,500 V DC.
为何1500V的直流铁路电气化没有3000V的那么受欢迎?
