Perhaps the Japanese feel especially fit that Shinkansen trains run in TAiwan seeing as they were the ones who set up the railways in TAiwan. Including the Alishan railway. And most of the trains in TAiwan have been Japanese as well.
Decades ago the fastest train (kuang hwa ) from TAipei to Kaohsiung took some six and a half hours (the more luxurious ChuKuang express with the American made General Electric diesel/electric locomotives took 8 hours) . The Kuang hwa was a Kawasaki built train if I remember correctly. It was one of those with no locomotive but every third or so car had an engine on the roof (diesel/ electric).
Then the western trunk line was electrified and English made General Electric electric locomotives did the main heavy duty work. Pulling ChuKuang as well as all the other long distance trains. Some Japanese made Tienche local trains started operating as well. Later the British made Tzechiang trains became the fastest trains in Taiwan taking around 4 hours to go from TAipei to Kaoshiung. These also had no locomotives but both ends had cars that had electric engines and driving compartments. These were later replaced by South African made trains (the locomotives were south african, the rail cars were made by TANG ENG iron works in Taiwan, like the Chukwang , Fushing and others) that once again had a locomotive (electric).
And now today we have the HSR as well. While on the east coast line we have the new Japanese made tilting trains the Taroko Express>.
Will someone who has been on one tell us bout those too? thanks
