Gebishi railway

The route required eight tunnels as long as 2,296 feet (700 m) with 3 percent grades and 28-degree curves (206.68 ft or 63.00 m radius).

In 1931, work started on a further western extension, from Lin'an to Shiping; it opened on October 10, 1936, the railway thus acquiring its "Gebishi" (Gejiu–Bisezhai–Shiping) configuration.

Yuguopu then became the new transhipment point between the 600 mm gauge Gebishi railway and Yunnan's metre-gauge rail network, while the old, less conveniently located connection at Bisezhai fell into disuse.

The track removed from the eastern end of the line was used to construct a new extension at its western end, from Shiping to Baoxiu (宝秀; also within Shiping County), in order to provide rail access to the new Longkouchong iron ore mine (龙口冲铁矿).

The regauging project started on January 1, 1970, using rails end equipment moved from other, recently torn down, metre-gauge lines in Yunnan.

In February 2010, freight service west of Lin'an Town (Jiashui County seat) ceased as well.

[4] The new standard-gauge Yuxi–Mengzi railway, opened in 2013, serves both Lin'an Town (Jianshui station) and Mengzi City.

Between these two cities it follows a route that is fairly similar to that of the narrow-gauge Mengbao line, but is straighter, due to greater use of tunnels and elevated sections.
