Breaking through a number of key core technologies, the railway construction heavy industry track system uses innovation to drive high-quality development!

It is pointed out in the report of the 20th National Congress of the Communist Party of China“Science and technology must be the primary productive force、Talent is the first resource.、Innovation is the first driving force，Thoroughly implement the strategy of rejuvenating the country through science and education、The strategy of strengthening the country by talents、Innovation-driven development strategy，Open up new fields and new tracks for development，Constantly shaping new momentum and new advantages for development。”In recent years，CRCHI Turnout Branch Focuses on R & D and Innovation，Break through a number of key core technologies，Drive high-quality development with innovation。

The first set of rack turnouts for mountain rail transit in China

Early October，The rack track turnouts designed and manufactured by CRCHI Turnout Branch have been applied on the rack track test line in Ziyang, Sichuan, and the dynamic adjustment test has been completed.，It will be officially opened in November.。The rack rail test line was successfully opened to traffic.，It marks the zero breakthrough of domestic cog rail traffic.，It provides a new impetus for the development of mountain rail transit industry in China.。

Rack rail turnouts for mountain rail transit laid in the plant

Railway Construction Heavy Industry Relies on Ziyang Rack Rail Test Line Project，Successfully independently developed 1435mm-1000mmGauge 50kg/mRail No.7 rack sleeve turnout。The turnout combines the characteristics of mountain rail transit and adopts a number of initiatives.、Original innovative technology。

Traffic opening test

Railway Construction Heavy Industry Turnout Branch started the development of rack turnout in 2018.，In 2020, the swing rack turnout system was independently developed.，Rack、The design of rack conversion mechanism and fastener system is original innovation.，It fills the gaps in the company and in China.，It is the only one with rack turnout design in China.、Manufacture、Unit of commissioning and on-track application performance。
