Farewell to "green" trains

NANJING, Jan. 10, 2016 (Xinhua) -- Two stewardesses pose for a selfie on the train No. 7101 in Nanjing, capital of east China's Jiangsu Province, Jan. 8, 2016. Train No. 7101 has been in service since the 1980s, running between Nanjing and Huangshan Mountain stations. It covered a distance of 371 kilometers with more than eight hours. As this slow-speed green train arrived in Nanjing for the last time on Saturday, many people came to say goodbye. (Xinhua/Wang Xin)
