复兴号动车
Fuxing bullet train
8月15日7时50分，牡佳高铁联调联试现场首组CR400BF-G型复兴号高寒动车组从牡丹江站缓缓驶出，这是复兴号高寒动车组首次参与（high-speed railway linking Mudanjiang and Jiamusi）联调联试。
It was the first time a Fuxing bullet train has run on China's easternmost high-speed line, which is located in an extremely cold region.
这是复兴号高寒动车组首次在中国最东端高寒高铁线路试跑。
据介绍，CR400BF-G型复兴号高寒动车组系在复兴号动车组“金凤凰”的基础上进行了高寒适应性技术提升。
The CR400BF-G Fuxing bullet trains are designed to withstand the climate in extremely cold areas that may be hit by blizzards and temperatures as low as -40 C. Designers chose materials with better airtightness for the equipment compartment, which can keep out the snow and cold air.
CR400BF-G型复兴号高寒动车组具有耐高寒、抗风雪等特点，能够在-40℃的天气下运行。设计人员为设备间选择了密封性更好的材料，达到防雪、低温防冻的目的。
Designers also installed sanding gear in the train, which may help increase traction and prevent the wheels slipping in snowy weather.
同时，设计人员还在动车组上安装了撒砂装置，能够在降雪天气增加阻力，防止车轮打滑。
