In each day, the testing train started from Huanggutun Station, the test with the speed level of 250km/h and less was conducted before reaching to Suizhongbei Station. After running into the enclosed section from Suizhongbei to Shanhaiguan, the test with the speed level between 250 and 275km/h were conducted back and forth on the down-going direction. The test with the speed level of 250km/h and less was conducted on the down-going direction while returning from Suizhongbei.  During the testing period on Beijing-Harbin Railway, No.1 car Mc12 is the head car towards Beijing, the up-going direction is at the head car, and the down-going direction is at the tail.  The actual maximum testing speed is 277.3km/h.
