The 5000 series is a series of Chicago "L" car built between 2009 and 2015 by Bombardier Transportation of Plattsburgh, New York. A $577 million order for 406 cars was placed in 2006.^[1] In July 2011, the CTA ordered 300 more cars (later increased to 308 cars) for $331 million as an option on the first contract.^[2][3]

The 5000-series reuses a numbering set used on four experimental articulated train-sets that were in service from 1947 to 1985. These are the first CTA railcars to have interior LED signs that display information such as the date, time, and the next station on the train's route.
