"We wish to offer French and Chinese companies occasional train solutions," said Xavier Wanderpepen, who is responsible for China-Europe rail freight activities at Forwardis, a subsidiary of France's national railway company SNCF Logistics.

"And we wish to work with China on the development of freight wagons with variable gauge capable of adapting to the situation in Western Europe, Russia and China. In a few years, we will be able to connect China and Europe in 10 days," Wanderpepen added.
