On June 6, 2022, local time in the United States, the Chicago factory of CRRC Sifang Co., Ltd. arrived at the Skokie Vehicle Maintenance Base of the Chicago Transportation Bureau. The Chicago subway batch cars manufactured by CRRC Sifang Co., Ltd. were successfully delivered to users.

In 2016, CRRC Sifang Co., Ltd. successfully won the bid for the Chicago Department of Transportation's 7000 series subway vehicle project in the international bidding. This was not only the largest rail vehicle procurement in Chicago's history, but also set a record for the largest number of subway vehicles exported from China to developed countries. , is an important breakthrough for China's high-end equipment in the international high-end market.

After the launch of the Chicago subway vehicle project, CRRC Sifang Co., Ltd. built a rail vehicle assembly plant in the south of Chicago, responsible for the total assembly and manufacture of 7000 series vehicles. Through the implementation of localized manufacturing and localized procurement, the project has driven local related supporting enterprises and created nearly 200 local jobs in Chicago.

The active suspension system is optimized, and using the new ultrasonic intelligent sensing technology, the vehicle can automatically detect the height of the platform, and automatically adjust the floor height of the compartment according to the height of the different platform, so that passengers can get on and off without a problem. The passenger service system has been upgraded, and the double-sided LCD display in the passenger room realizes dynamic map broadcast; special visual and sound indication functions are set up to facilitate the ride of the hearing-impaired and visually-impaired; passenger seats with optimized horizontal and vertical layout, LED lighting, and reasonable layout The handrails, and better running stability, greatly improve the passenger riding experience.

smarter

The real-time Ethernet control system is used for the first time, which has stronger network transmission and data processing capabilities, and improves the intelligent level of fault diagnosis and operation and maintenance.

safer

The vehicle's fire resistance meets the strict NFPA130 American standard. Under the condition of overloaded load, the floor structure can withstand fire for 30 minutes; the vehicle body adopts a regional customized load strategy, and a new energy-absorbing structure has been developed. The crash performance meets the strict ASME RT-2 American standard. Require.

The new car also adopts a series of targeted designs, has strong environmental adaptability, can adapt to extreme weather conditions such as -32 ℃ high cold and snow storms, and has the ability to pass the main line with an ultra-small radius of 25 meters and a full-load rescue function of 40‰ large ramps. , which can better meet the complex local route operation environment in Chicago.

According to the plan, the first batch of vehicles of the project is expected to be delivered in June 2022, and will be manufactured and delivered in batches according to the user's operational needs in the later period.Editor/Ma Xue
