北京
Late at night on January 15, the maintenance workers were working feverishly to inspect and maintain a train of high-speed trains. The institute is responsible for the maintenance and repair of some high-speed trains of Beijing-Guangzhou high-speed railway and Beijing-Shanghai high-speed railway, so it is imaginatively called “high-speed railway hospital”, and the maintenance workers are also known as “dynamic car doctors”. In order to let travelers go home safely and smoothly for the Chinese New Year, they are scrambling to be busy, and do their best to ensure the normal operation of high-speed rail coaches during the Spring Festival.
