During the Spring Festival travel rush, the high-speed railway EMU trains driven by train drivers race along at high speed, but few people know that there is also a group of train drivers who operate slow trains, quietly safeguarding a key link in train circulation. From Jinan Railway Station to the Jinan Passenger Car Service Yard, the whole distance is only 5 kilometers, passing multiple tracks and turnouts. The shunting locomotive driven by Xu Bingyan must always maintain a speed below 30 kilometers per hour. When coupling with railcars, the speed needs to be reduced step by step, and at a final distance of one meter the speed must drop to below 1 kilometer per hour, which requires precise operational skills.
