Green-skinned train



The terms green-skinned train and green train  refer to a type of design which used to be the mainstay of the passenger railway fleets of China and other communist countries during the Cold War. These words carry connotations of slow travel on old vehicles with few amenities, most notably lacking air conditioning. Despite these connotations, some newer trains have been painted green for nostalgic purposes.
