Last call for China's quaint 'green' trains

China has made great efforts in recent years to develop its high-speed railway network and most major cities are connected by bullet trains.

Despite the rapid expansion of China's modern system, some older low-speed trains - which Chinese call "green-skin trains" because of their green appearance - still carry passengers in remote areas.

In contrast to high-speed trains that carry mostly urban travelers, the "green-skin trains" possesses a special appeal because the passengers are largely rural people who enliven the carriage with lively conversations and loud laughter.
