CTA Flxible Metro E # 6008

10/22/09 Engine Detroit Diesel Series 50 with ZF ECOMAT HP-590 Transmission In 1995, the CTA purchased what would be its last order of new high floor buses. A contract was awarded to Flixible Corporation for 330 Metro buses.
Starting in 2004, a portion of the 6000-series began to undergo a mid-life rehabilitation. In addition to mechanical improvements and a new coat of paint, the buses received LED destination signs which offer greater visibility and reliability compared to the flip-dot signs originally installed in the buses.
Retirement of some non-rehabbed 6000-series buses began in 2008. The timeline for full retirement of the series has yet to be determined.
