(Yicai Global) Feb. 20 -- A unit under the world's largest rolling stock manufacturer, China's CRRC, has received a second order from Sydney for its double-decker trains.

CRRC Changchun Railway and Australian partner Downer EDI have been contracted to design and manufacture 17 new trains and provide post-delivery maintenance, state-backed China News Service reported, citing a statement from the CRRC arm. The firm did not disclose the deal's worth.

The two partners landed their first order for 24 of the two-story rolling stock in December 2016, and have shipped a total 732 passenger trains to Australia to date. The vehicles have stood the tests of time and have been well received by the country's local governments and passengers, which helped them land the latest contract, the statement added.

CRRC Changchun is China's primary developer of railway passenger trains. It set up its Asia Pacific headquarters and a rolling stock engineering research base in Melbourne in 2017 to provide technical support for projects in the region.
