Yuntong Bus is a bus of Beijing Xianglong Bus Passenger Transport Co., Ltd., which belongs to private enterprises. Xianglong Company was originally called Express Company, so all its subordinate buses started with express delivery.
Bus mobility is the backup vehicle for the fleet of passenger transport companies under Beijing Public Transport Group Corporation, including Passenger Transport Company I, Passenger Transport Company II, Passenger Transport Company III, Passenger Transport Company IV, Passenger Transport Company V, Passenger Transport Company VI, Double-decker Bus Company and Bafangda Company under Beijing Public Transport Group Corporation. All these companies have their own motor vehicles except Octopus. When the official car is temporarily used due to maintenance, failure or insufficient capacity during peak hours, there is no fixed line, so it is called maneuvering.
The feeder bus is the bus of Beijing Bafangda Passenger Transport Company. Because there are only 9-prefix sections, many lines should be injected into the feeder bus and the section, such as 930,930 sections and 930 sections. The 944 branch train represents 944, and the running line is basically the same as 944, but some sections are still different.
