College students chat on the train No. 7505 as they are on their way home for winter vacation in northwest China's Gansu Province, Jan. 10, 2020. The train No. 7505, which travels from Lanzhou to Wuwei, is a four-carriage ordinary train. The train, which links more than a dozen small stations between Lanzhou and Wuwei, runs 290 kilometers in 5 hours and 27 minutes. The full fare is 18.5 yuan (about 2.7 U.S. dollars), with the lowest fare being 1 yuan. It has been running for nearly 40 years since the 1980s, carrying nearly 10 million passengers. During the Spring Festival travel season, the ordinary train offers passengers an alternative choice to go home at a cheap fare. (Xinhua/Ma Ning)
