Features and Natural Landforms

The Alishan Forest Railway has the following important features, which make it not inferior to any of the railways listed as world heritages. We hope that citizen could realize our precious cultural asset—Alishan Forest Railway, and come to enjoy the trip.
 

The slope is steep and the curve is small

The Alishan Forest Railway is 71.6 kilometers long and is divided into two sections: level ground section and mountain section. From Chiayi Station to Zhuqi Station, the length is 14.2 kilometers and the terrain is flat and flat, so this section is called level ground section, of which the curved paths and slopes are very normal and the smallest radius of curvature is 160 meters and the steepest slope is 2%. The length from Zhuqi Station to Alishan Station is 57.2 kilometers. Because ridges and peaks rise one after another and the terrain is steep, this section is called mountain line with a maximum slope of 6.25%.
 

Duli Mountain spiral

Due to the steep mountains, the track could not be elevated and it is necessary to wind along the terrain. The five-kilometer long track around the Duli Mountain has to be spiraled upward to the top of the mountain in three circles. When the train winds round the mountain, passengers on the train can see the Zhangnaoliao Station under the mountain for three times from the left and right side of the train. Then the train leaves the Duli Mountain along the track in the shape of "8". At this time, passengers can see the Zhangnaoliao Station for the fourth time.
 

Horseshoe bend

There are many places along the railway line designed with horseshoe bends, such as the 180-degree bend at the 17 km milestone of the Alishan Railway on the Zhuqi Jiaren Mountain. The railway winds along the 180o curve to spiral upward.
 

Switchbacks

 After Pingzena Station the track zigzags forward. When traveling along the third switchback, the train sometime pulls forward and sometimes pushes back to Alishan. "The Alishan train hits the wall," as the saying goes.

The Alishan Forest Railway runs from Chiayi Station, which is 30 meters above sea level, to Alishan Station, which is 2,216 meters. Travelling by train along the Alishan Forest Railway, passengers can see the changes of plants of three forest forms, tropical, temperate and cold forests, and the beautiful landscape of mountains and valleys.
 
Alishan is characterized by tropical, subtropical and temperate forests. In the area from the level ground to the 800-meter-high Duli Mountain is a tropical forest. The plants in this area are represented by banyan, longan, acacia and bamboo. In the area from the Duli Mountain to the 1,800-meter-high Pingzena is the subtropical forest. The representative trees include camphor, tanoak, nanmu, Chinese fir, and cedar. In the area from Pingzena to 3,000 meters above sea level is the temperate forest, where the cedar, red, cypress, Taiwan fir, hemlock, and armand pine are the main types of trees.
 
Every year from mid-March to mid-April, the Alishan Flower Season kicks off with cherry blossoms. Taiwan cherry, Kuril cherry, Yoshino Sakura, Oshima Sakura, and Yasu Sakura are open to the public. From April to May, Taiwan Pleione, Rhododendron morii Hayata, Common Foxglove, Crocus Tritonia, and Chinese Wisteria compete for diffusing fragrance. In addition, there is a "Taiwan Pleione Natural Reserve" on the rock wall between the 5th and 10th tunnels of the Alishan Mianyu Line. Taiwan Pleione (one leaf orchid) is Perennial herb. Because there is only one leaf grow under the flower, so it is called one leaf orchid. It is endemic to Taiwan and is very precious.

Steam locomotives

The Alishan Railway runs up a very steep slope. In order to adapt to this special environment, the Office of the Taiwan Governor-General purchased the 18-ton and 28-ton Shay vertical cylinder steam locomotives manufactured in 1881 from the American Lima company in 1911. This early-made locomotive was equipped with vertical steam cylinders on its left or right side and cylindrical compressed air reservoir like a torpedo on the same side. There is a trademark on the large trumpet shaped chimney at the front of the locomotive. To function well for climbing the steep slope, the lower end of the steam engine is equipped with a bevel gear to match the axle, so as to use rotation to get the locomotive move forward.

Narrow gauge railway

The Alishan Railway is Asia's "highest" narrow-gauge mountain railway, surpassing the Indian Darjeeling Himalaya Railway.
 

Animals

The Alishan area is rich in forest resources, so it is a good habitat for wild animals. However, due to the long-term artificial exploitation of the forests in middle and high altitude areas, the ecological environment has been damaged seriously, causing the animals to migrate to high-altitude mountainous areas. According to preliminary investigations, there are 19 kinds of mammals in the Alishan area, among them Formosan macaque and Formosan Reeve's muntjac are protected animals. There are 75 species of birds, among them the six endangered species are black eagles, Hodgson's hawks, Swinhoe's pheasants, Mikado pheasants and Tawny fish owls. There are eight species of amphibians and reptiles, among them Buergeria robusta is rare and protected animal. There are 194 species of butterflies, accounting for more than half of Taiwan's butterflies. There are 6 species of fish and 2 species of crustaceans, among them Chinese mountain pit viper, collared bush robin, Candidiopotamon rathbuni, Hynobius arisanensis, white-eared sibia and Taiwan black bear are endemic to Taiwan.
