In 1967, Hsing Ta Cement Co. Ltd. applied for a feeder of railway in order to transport minerals. Than the cement factory was set up. The station yard of Nansincheng Station (Su-aosin Satation) started the business operation on April 15, 1968

The North Link Line construction with a total length of 82.3 kilometers started on December 25, 1973, and it was built from 2 ends which are the north end and south end simultaneously. It started from Nansincheng Station in the north. RSEA Engineering Corporation was in charge of the whole construction process with expected total construction process time period of 4 years (The North Link Line was completed on February 1, 1980).

Since the name of the Sincheng Station on the North Link Line was similar to the name of the Sincheng Simple Station managed by Nansincheng Station, the name of Sincheng Station on Yilan Line changed to Shenghu Station, and the name of Nansincheng Station changed to Nanshenghu Station by following the order of Department of Transportation on June 1, 1975. After the North Link Line was completed on February 2, 1980, Nanshenghu Station became the intersection of the North Link Line and Yilan Line. As the goods freighting and passenger service operation grew, Nanshenghu Station became the 2nd class station on May 1, 1981

 In order to satisfy the locals requests and passengers’ convenience to distinguish the stations, the name of Nanshenghu Station changed to Su-aosin Station, and the name of Shenghu Station changed to Sinma Station on January 1, 1982 (Nansincheng Station on April 15, 1968→ Nanshenghu Station on June 1, 1975→Su-aosin Station on January 1, 1982). The new station yard started to operate on November 14, 2003.

The Scenic Area near to Su-aosin Station is Wulaokeng where the tourists do water playing, BBQ, and camping. Recently, Yilan County Government holds Ilan Green Exposition here. Wulaokeng is vast, the river is pure and clear, and there are 8 theme halls within a guild hall. The theme of Ilan Green Exposition is different every year.

Wulaokeng River is flowing out of the root of the mountain. It provides the life energy to the lives here and makes Wulaokeng a wonderful place. Therefore, the tea plants are everywhere on the root of the mountain with the wind and fog. There are many kinds of tea with the best quality here. Thus, the tea shops are as plenty as the tea plants. If you like tea, you can come here and try it. You may find that it is different from the tea in other places. People always say that tea is good for human’s body. To drink tea after meals helps your diet with having stomachaches.
