CTOnews.com, November 24, according to CCTV news, China's first gear rail train (electric passenger car) has been successfully offline in Ziyang, Sichuan Province, which is the first new type of vehicle in China with completely independent intellectual property rights, filling in the gap in the field of gear rail trains in China.

The off-line toothed rail train will be used between Dujiangyan and Siguniang Mountain, the first toothed rail railway in China (referred to as the "du Si" line).

CTOnews.com learned that the tooth track is a kind of mountaineering railway. In general, the slope that the railway can climb is about 4% to 6%, and it can also cross a short section of 9% from time to time. The tooth track railway places a special tooth rail on the sleeper in the middle of the ordinary track. A locomotive running on a gear rail, equipped with one or more gears that mesh with the tooth rail. In this way, the locomotive can overcome the problem of insufficient adhesion and pull the train up a steep slope with a slope of 48%.

The second China Railway Institute carried out the gear rail train test in July this year. The Ziyang gear rail train test line project, which was built by the Scientific Research Institute (Industrial Center) of the second China Railway Academy as the main responsibility unit of EPC, has been completed. After testing, the whole line has initially met the test conditions for the gear rail train on the upper track.

The "du IV" line starts from the Dujiangyan station of Chengguan Express Railway in the urban area of Dujiangyan, ends at Siguniangshan Town, Xiaojin County, Aba Prefecture, and connects Dujiangyan City, Wenchuan County, Wolong Special Zone and Xiaojin County, with a total length of 123.18 km and 12 stations. The first section is expected to open at the end of 2023 and open to traffic in 2026. Upon completion, tourists can directly transfer to this gear rail train at Dujiangyan Station to go to the Siguniang Mountain Scenic area. The travel time between the two places will be reduced from 5 hours to 2 hours.

The train adopts the dual traction mode of "wheel rail + gear rail". The maximum running speed can reach 120km / h in the wheel rail section and 40km / h in the gear rail section.
