Which is the longest bus in Nanjing?

A bus line has a total length of 54 kilometers and 55 stops along the way, and it takes 5 hours to drive back and forth. When the reporter heard the above introduction of Nanjing Passenger Management Department, he was shocked: I took the bus 10 for many years in Nanjing, but I didn't expect there to be such a long bus line. The longest bus line in the city opened by Nanjing Zhongbei Bus Company is called the South Upper Line, which starts from Nanjing Railway Station and ends at Shangba, Changjiang Township, Qixia District. Speaking of this "long-distance" bus, there are also many comrades on the suburban line of Zhongbei Bus. Shangba used to be Jurong's territory. In the mid-1980s, regional adjustment was incorporated into Qixia District of Nanjing. With the continuous expansion of Nanjing, bus lines gradually extend from Longtan to Shangba. At present, there are 15 buses on the southern line, and the departure time of the railway station is from 5: 50 am to 7: 00 pm. Because the line is too long, it takes two and a half hours to drive one way. When the last bus arrived at Shangba in the evening, it was already past nine o'clock in the evening. Therefore, Zhongbei Company specially recruited a group of drivers and flight attendants from Shangba, and went home to rest after the last bus at night. The South Line is also the only one of CNR's existing manned ticketing routes. The fare starts at one yuan, and the whole journey only costs 6 yuan money.

At the main station of the Southern Railway Station, the reporter met the driver Zhu Shifu who was about to get off the train. He is the elder of this line. He told reporters that the biggest feeling of sports cars for so many years is that the road conditions are complicated and very tired. The southern upper line passes through cities, urban-rural junctions, towns and villages, and even runs on the dam for two or three kilometers. There are rivers on both sides of the dam, and the narrowest place is only 6 meters, so you should be very careful when driving. The first bus on the dam leaves from the station at 5: 00 in the morning. The driver must get up at 4: 00 and arrive at the station in advance to prepare for the departure. In case of delay, the driver will be fined 100 yuan. Master Zhu has never been late for driving for so many years. At noon, he ate some food brought back from Shangba's house at Nanjing Station. The passenger waiting for the bus, Mr. Chen, is from Shangba. He runs a beauty salon in a small town. Today, he caught the early bus to Nanjing to wholesale a batch of hairdressing products. He usually goes to town once a month or two. Because he always takes this route, he knows almost all the drivers on the bus. While speaking, another bus from Shangba pulled into the station. Ms. Wang took her daughter to Nanjing to buy wedding supplies. The beaming mother and daughter told reporters that they would come to Nanjing because of the convenient transportation and any big items added at home. The comrades of Zhongbei Bus proudly told reporters that although the southbound line runs in the suburbs, with the increasing radiation from Nanjing to the suburbs, many rural people are studying and doing business in the city, and the traffic is very frequent, especially on weekends. Therefore, the southbound line has become the company's "golden doll", with an average of 700-800 long-distance passengers carrying fares above 4 yuan every day, and a bus leaves every 20 minutes during the afternoon rush hour.
