DALIAN, Aug. 3 (Xinhua) -- A deal to export 15 locomotives made by China Railway Rolling Stock Corporation (CRRC) to New Zealand was signed on Tuesday in China's northeastern city of Dalian, the company said.

It was the fourth group of locomotives that CRRC has exported to the country, raising the total number it has exported to New Zealand to 63.

The 15 high-end locomotives will have upgraded brake systems and improved energy conservation, according to CRRC Dalian Co., Ltd.

A joint venture with investment by CRRC Dalian and a New Zealand company was set up on Tuesday to provide technical consultancy and maintenance service for locomotives in New Zealand.

CRRC, formed from the merger of former rivals CNR Corporation and China CSR, has been actively bidding for contracts in overseas markets in recent years and has sold equipment to more than 100 countries and regions.
