Building roads and bridges, traveling in all directions. As a major artery of the national economy, railways are the backbone of major livelihood projects and comprehensive transportation systems. The railway transportation for the Mid Autumn Festival and National Day Golden Week starts on September 27th and ends on October 8th, lasting for 12 days. The national railway is expected to send 190 million passengers, and the railway passenger flow shows a strong growth trend. Behind the bustling crowds of people during the Golden Week of the Mid Autumn Festival and National Day, there is a group of railway workers who are steadfast in their frontline positions. They are diligent, selfless, and dedicated, guarding the travel routes of thousands of passengers, witnessing the journey of China's railways. The Yangtze River Bridge in Jiujiang, Jiangxi Province, is the "throat" of the main artery of the Beijing Kowloon Railway and a transportation hub connecting the north and south of the Yangtze River. During the Mid Autumn Festival and National Day, the daily average ship flow of the Jiujiang Waterway on the Yangtze River has significantly increased, with a continuous stream of ships of all sizes passing through the bridge. To ensure the safety of the bridge, 18 navigation lights were installed on the bridge to guide passing ships smoothly. Chen Yu, the bridge and tunnel worker of the Jiujiang Bridge section of the National Railway Nanchang Bureau, is responsible for the maintenance of these 18 navigation beacon lights. On the bridge, the train was speeding, and the passengers were rushing towards "Poetry and the Far Distance". Under the bridge, Chen Yu and his colleagues held their positions and came to the Jiujiang Yangtze River Bridge as usual to inspect the navigation lights. They walked and climbed through the beam of the bridge, which was more than 20 meters high from the surface of the Yangtze River. They followed the steep steel inclined ladder suspended in the air to the pier below the bridge, and then skillfully climbed up the narrow vertical maintenance channel. By the beacon light, Chen Yu leaned out of the inspection channel and without hesitation bent forward 90 degrees, facing the rolling river water under his feet. At first, when I saw the river, I would feel dizzy and my feet would become soft. Now I'm used to it, "Chen Yu said. He held a screwdriver in his hand, while checking whether the beacon lights were loose, he wiped them clean with skillful and gentle movements. Railway maintenance personnel are repairing navigation lights at the Jiujiang Yangtze River Bridge. The interviewee provided a picture since the opening of the Beijing Kowloon Line in 1996. Chen Yu has been steadfast on the Jiujiang Yangtze River Bridge for 27 years, wholeheartedly guarding 18 navigation lights. Nowadays, LED lights are commonly used for navigation lights, which are more energy-efficient, environmentally friendly, and have a longer lifespan. We need to maintain them regularly. Every maintenance takes a day, and we must remain fully focused during the process. As long as one light goes out, it may cause a ship to collide with a bridge. We need to repair it in the shortest possible time to ensure its normal lighting and ensure the smooth passage and railway safety during the two festivals, "Chen Yu said. The quality inspector of the high-speed train stayed up late at night, and the lights in the maintenance shed of the high-speed train were brightly lit. The backrest of the seats here on this train is a bit loose and needs to be repaired as soon as possible. Chen Puyan is a quality inspector of the train and needs to recheck the vehicles repaired by the train's mechanics. He needs to ensure that there are no faults before the train goes online. At 3am, in the carriage of the CR400AF Fuxing intelligent high-speed train, Chen Puyan occasionally looked up, bent down, and squatted down, from the electric tea stove to the air conditioning, from the car window to the toilet, from the lighting to the insulation box... Chen Puyan walked in a fancy way in the carriage, carefully examining every component of the high-speed train. He said, "During holidays, there is an increase in the number of passengers choosing to travel by railway. We must carefully inspect, eliminate faults, and ensure that they move
