Alishan Mountain Railway, Taiwan.

 

Alishan Mountain Forest Railway is regarded as one of three mountain climbing railways. Traveling along the 72-kilometer-long railway, the train climbs from 30 meters (about 98 feet) to 2,450 meters (about 8,038 feet) above sea level. Its gradient is so great that it is rarely seen in the whole world. From the bottom of the mountain to the top, the train crosses four forest areas – tropic, subtropical, temperature and the frigid zone. While climbing up the forest scenery is spectacular including eucalypt trees, coconut trees, conifers and the Frigid Zone forest. Along the way, the railway passes through 50 tunnels and over 77 bridges.
