Bombardier is supplying 706 new rail cars (known as the 5000-Series) to the Chicago Transit Authority (CTA), the second largest public transportation system in the United States, covering the City of Chicago and 40 surrounding suburbs. The new vehicles will replace older rail cars, some more than 30 years old.
These next-generation rail cars will be the first in the CTA’s fleet to utilize alternating current (AC) propulsion, a technology that permits dynamic braking regeneration, lower energy and maintenance costs, and improved reliability. The new fleet of cars also will be equipped with an active suspension system to ensure that the car floor is level with the station platform during boarding, allowing passengers to board the train more easily.
Other features of the new cars include greater capacity, better communications systems, increased security and real-time diagnostics to improve reliability.
