※ This video is part of <Extreme Job - Busan Subway Depot Part 1> broadcast on July 13, 2011. ▶ Busan Metro Depot. Here, subways are disassembled every day, meticulously maintained down to the smallest parts, and old dirt is removed to perform heavy maintenance work. Heavy maintenance work is the largest-scale subway maintenance work, which involves separating and repairing the car body and the bogie section where all mechanical devices, including the engine, are installed. The subways that arrive at the depot are first separated by each parts team. After the parts are taken from the car, the cars are separated one by one, and the separated cars are moved along the rails to the place where the car body and bogie are separated. The disassembled car body is moved onto four tripod-shaped supports. During the moving process, if the signals of the overhead crane operator who lifts the car body and the workers who connect the crane to the car body do not match well, a major accident can easily occur, so caution is advised. ▶ 2 minutes before arriving at the final destination and entering the depot. There are people who move quickly during the short time when passengers are getting off. They are the cleaning staff. The two or three cleaning staff waiting at the final station have to finish cleaning during the short 1~2 minutes that the last subways stay at the final station. If they can do basic cleaning, it would be easy work. They say that if they meet a drunk passenger who comes home late after drinking, the cleaning that day becomes twice as difficult, so they are always anxious. ▶ Vehicle inspections are conducted every day without fail to ensure that the vehicles that run every day can greet citizens in the best condition. While checking for vehicle errors from the driver's seat and thoroughly checking the condition of the broadcasting system, air conditioning, and fluorescent lights, the departure time approaches as the sun rises. ▶ The central control center that checks the subway operation time and organizes the subways in operation. It is a controlled area where hundreds of vehicles can simultaneously monitor all the currents and situations. Busan's special features make them even more alert on baseball game days. At this time, a problem with the signal exchange device occurs, so the emergency inspection team is dispatched, changing all electronic methods to manual methods, and overcoming the crisis by organizing the vehicles one by one via phone and radio. ▶The last day of the water line inspection. Vehicle assembly work is in full swing. Perfect assembly of each part is essential for safe operation! The work of attaching the body and bogies to each subway car is in progress. Something went wrong during the assembly of the bogie and the body. The sound of air leaking can be heard in the air system between the body and bogie, which is connected by air absorption! If they're not careful, they might have to disassemble the vehicle again... Will the workers be able to finish assembling the vehicle safely? ✔ Program name: Extreme Job - Busan Subway Vehicle Base Part 1 ✔ Broadcast date: July 13, 2011 #GolladyeonDocumentary #ExtremeJob #Busan #Subway #Terminal #Inspection #SupplyLine #Control Center #SubwayMaintenance #Maintenance #VehicleDisassembly #VehicleBase #UrbanRailroad #SubwayCleaning #SubwayInspection #Assembly #SubwayAssembly
