2月1日,在美国芝加哥的西部大道车站,一辆火车从“着火”的铁轨上驶过。连日来,严寒天气肆虐美国中西部和东部地区。芝加哥在1月30日出现零下30摄氏度的极低气温。铁轨因寒冷而收缩,甚至冻裂,铁路工作人员通过“火烧铁轨”使铁轨复原,以确保铁路交通正常运转。[新华社 汪平 摄]

A U.S. Metra train runs on tracks on fire at Western Avenue station in Chicago, the United States, on Feb. 1, 2019. Chicago's railway system uses gas-fed heaters that run alongside the rails to keep them warm, in case frozen tracks cause traffic disruption. The biggest city in the U.S. Midwest was hit by the polar vortex with minimum temperature reaching record low of minus 30 degrees Celsius on Wednesday. (Xinhua/Wang Ping)
