on october 6, the yangcheng evening news all-media reporter learned from the guangzhou metro group guangdong intercity operation company that recently, after more than 10 consecutive hours of testing, the guangqing intercity north extension line successfully completed a step-by-step speed increase test, marking the the guangqing intercity north extension line has achieved major project node goals in the dynamic acceptance stage and is about to enter the signal system test stage.
it is understood that the guangqing intercity north extension line has a total length of 19.7 kilometers and a total of 4 stations, namely yanhu station, zhouxin station, feixiashan station (reserved station) and feixia station, with a design speed of 200 kilometers. /hour. after the opening of the guangqing intercity north extension line, it will be connected and operated with the existing guangqing intercity, which will help further optimize and improve the layout of the pearl river delta intercity network, and enhance guangzhou's radiation and driving force for qingyuan's central urban area and various groups.
according to guangzhou metro, during the step-by-step speed increase test of the guangqing intercity north extension line, the crh2j-0205 comprehensive inspection train conducted round-trip tests at 5 speed levels from qingcheng station to feixia station. the train operating speed increased from 160 kilometers per hour to 160 kilometers per hour. the speed was increased to 200 km/h, and finally to 220 km/h, reaching 110% of the engineering design speed, which verified the safety margin of the project. on-site inspection data showed that during the train test run, indicators such as wheel-rail relationship, pantograph-network relationship, vehicle stability, track quality index, and catenary smoothness all met industry standards.
guangzhou metro stated that with the complete success of the step-by-step speed increase test, the guangzhou-qing intercity north extension line is about to enter the signaling system test stage. next, we will do our best to carry out follow-up commissioning work to provide guarantee for the high-quality opening of the guangqing intercity north extension line.
