CHONGQING — A China-Europe freight train loaded with new 40-foot, 35-metric-ton general-purpose automobile containers departed from Chongqing in Southwest China earlier this week, marking an innovation that makes the transportation of vehicles by rail more efficient.

The containers were carrying 182 automobiles from China Changan Automobile Group Co Ltd, an automaker headquartered in Chongqing, a major automotive manufacturing hub.

With the new containers, Chongqing is boosting the capacity of China-Europe freight train services to meet growing demand for automobile export transportation.

The containers are an innovative piece of equipment designed for the export of domestically-made passenger cars, according to Guan Yu, manager of the marketing department of the Chengdu branch of China Railway Container Transport Corp Ltd.
