China is planning to spend CNY3.5tn ($525.9bn) on the nation's railway network over next five years.
The Ministry of Railways said the government will invest an average of CNY700bn ($102bn) annually.
China intends to have more than 120,000km of track by 2015, including 30,000km of new track, according to english.cntv.cn.
The ministry's report noted that railway investments in the future will include the construction of high-speed rail track and upgrades of ageing railways.
The government will focus on provincial or lower-level projects, and will also encourage local governments and private firms to become the main investors.
