On 22 April, the long-term orbital traffic traffic line 4 southerly completed a three-month aerial test operation, with completion and initial pre-operational security assessments to be conducted in May, and after two receipt and inspection evaluations, the fourth linear service will enter the start of the pilot operation.

In order to achieve the early commencement of the shuttle operation of the fourth linear operation, since January this year, the orbital transport group, in accordance with the requirements of the Ministry of Transport, has been carrying out pre-communicated work, has completed the consolidation of the equipment system, completed the 20-day running of the run-up, completed the initial pre-operational security assessment pre-operation inspection, completed the air-loading operation, etc., and ensured the high quality of the G4 operation through pre-service inspection and initial pre-operation security assessment.

Line 4 is an extension of line 4, with a full length of route of 4.485km, primarily to facilitate the development of the mission by strengthening links between the central urban areas and the NSG. The route runs from the south end of the day-to-day workstation to the south end of the day-to-day new routing station, with a total of five stations, an average of 864 metres between stations, all of which are high-side wheeled. The garage stations are the well-being major road station, the nascent road station, the epoch station, the former 10 Ribourg station and the nascent road station, respectively, where the 6 line is being constructed. A further 12 LBC buses are purchased for vehicles.
