Beijing-Shanghai High-Speed Railway Co. Ltd., the operator of the Beijing-Shanghai high-speed railway, has launched preparations for an initial public offering (IPO) on the mainland stock market.

京沪高铁有限公司，京沪高铁的经营者，已做好在大陆股市首次公募的准备。

The Beijing bureau of China Securities Regulatory Commission, the country's stock market regulator, on Tuesday published information on the pre-listing tutorial services provided by CSC Financial Co. Ltd. for Beijing-Shanghai High-Speed Railway Co. Ltd. (BSHSR) on its website.

With high-quality assets and stable cash flows, the BSHSR has been turning a profit for more than three years in a row and is eligible for an IPO, according to the CRC.

The listing process is said to be part of a new "asset securitization" plan designed to reduce the corporate debt of China's state-run companies.

With a total length of 1,318 km and linking the capital with the eastern coastal economic hub of Shanghai, the Beijing-Shanghai high-speed railway has carried 940 million passengers since starting operation in June 2011.

No timetable for the IPO has been disclosed yet.
