鐵路以直流1500V電氣化為主的國家,也只有日本法國荷蘭而已
在歐洲有直流電氣化鐵路的國家,主流是直流3000V(比利時/西班牙/義大利/波蘭/捷克斯洛
伐克/俄羅斯等)
英國本來要在1920年代也學鄰國法國荷蘭那樣的直流1500V鐵路電氣化,最後卻因為種種原
因沒做,反而是戰後的電氣化以交流25KV50HZ為主
(不過我認為,英國南部那一批還在用直流750V+第三軌的一般鐵路路線,可以轉成1500V直流
化+架空線化)

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.
為何1500V的直流鐵路電氣化沒有3000V的那麼受歡迎?
