Rail freight services from Chengdu to Lodz, Poland and back are expected to make 300 trips in 2016, according to the State Council, China's cabinet.

The Chengdu-Lodz run, which opened in April 2013, has brought precision instruments, IT products, and clothes from China to Europe, and food and beverages from Europe, according to Chengdu port and logistics office.

The rail line is expected to bring cars from Germany to Chengdu in the future.

"Currently, the train runs twice between the two cities every week, which will increase to five times a week - or 300 times in 2016," said Chen Zhongwei, an official with the office.

Mr Chen said the freight service will explore two new routes to connect the city with Germany and the Netherlands.

A number of cities - including Chongqing in southwest China; Wuhan, Zhengzhou and Changsha in central China; Shenyang and Harbin in northeast China - have rail freight services to Europe.
