The Yunling Line is a single-track mountain branch, eighty-seven kilometers long, with seven stations and only one night train in each direction every day. On the night of December 23, 2011, train 8623 lost a carriage. It was on the consist sheet when the train departed, but gone by the time it reached Wudu Station. An escort aboard the train vanished with it. The case file contained only one line: "Consist record clerical error. Employee resigned voluntarily." Fifteen years later, Lu Zheng, a rail-inspection foreman, struck the sixteenth carriage with his hammer. The sound was dull. It wasn't a crack. The material was wrong. Someone had replaced this carriage. Its number was 344217, and the scrapping ledger said it had been destroyed on December 28, 2011. Yet there it was, coupled to the tail of the night train, waiting to depart. He ordered the train held. Four days later, a suspension notice arrived, citing three reasons, each perfectly reasonable. He could hear cracks, looseness, and differences in metal, but not the human heart. Yet the first blow of his hammer had cracked open the secret the entire line had kept buried for fifteen years: the carriage hadn't vanished; someone had changed its number. The man hadn't vanished either; someone had taken over his employee number and lived for fifteen years. From the first carriage to the seventh station, from a single consist sheet to an empty number, he pursued the truth. Which track was the final carriage on, really?
He had been hammering the car for nine years. When the hammer fell for the thousandth time, the hammer told him: This car died once fifteen years ago.
Three-height weighing list, difference of four tons | Lu Zheng took Cui Mingliang to Sanhe Station on the 8623 Timing, and asked the freightman Zou Quan about the strange thing about the "shortage of four tons" of tarpaulin wires but two intact lead seals and no tears in the tarpaulin; he watched the re-weighing time "twenty-two nineteen" - just falling During the stop at the Sanhe Sanhe Station, the conclusion of "leakage along the way" was overturned in public: the four tons did not get on or off the bus, but someone moved a number in three minutes; at the end of the chapter, the wall clock read 3:07, and the next train of 8624 entered Sanhe at 07:02, leaving only four hours.
During the night shift train inspection, Lu Zheng hammered out that the sound of the hammer on the sixteenth car was wrong, detained the car, checked the car number, and bumped into the train conductor Cen Yu who was looking for his father. Duan Li transferred the bus away overnight, and he was suspended. Cen Yu handed over her 2011 bus pass - the photo was of her father, and the job number belonged to another person.
Lu Zheng, the train inspection foreman, has been hammering the car for nine years, and you can hear the cracks, looseness and material of the hammer. On the night of October 4th, he struck the 16th verse of 8623, but the sound of the hammer was wrong. It's not a crack, it's the material. The car number is 344217, and the scrappage ledger states that it was destroyed on December 28, 2011, but it is now hanging on the tail of the night train, waiting to depart. How did a carriage that had been destroyed for fifteen years come back online? On which track did the lost carriage of that train stop fifteen years ago?
