The future train cars, the 7000-series, have been ordered. Each 7000-series rail car will feature LEDs, 37 to 38 seats, and is a hybrid of the 3200-series and 5000-series. The design and arrangement of seats were modified to improve ergonomics and increase leg room. Enhanced air conditioning will circulate air more efficiently during hot summer days. Laser sensors above the doors will count the number of passengers, allowing the CTA to track passenger volumes and change its schedules accordingly. State-owned manufacturer CRRC Sifang America (China Rail Rolling Stock Corporation) won the contract, besting the other major competitor, Bombardier from Canada by $226 million. Concerns have been raised over possible malware, cyber attacks, and mass surveillance by the Chinese government. However, the computer and software components and the automatic train control system will be made by U.S. and Canadian firms. The contract requires ten prototypes to be delivered by October 2019. If the rail cars prove to be acceptable, then full production cars would be delivered starting in October 2020, at a rate of 10 cars per month. The base order is for 400 cars and will be used to replace the 2600-series cars. If the CTA ordered the additional 446 cars, they would replace the 3200-series cars.
