CTA Retiring 2200-Series Rail Cars With Loathsome Accordion Doors After 44 Years Of Service

The Chicago Transit Authority is throwing a retirement party on Thursday for its oldest fleet of rail cars: the 2200 series.

According to the CTA, the 2200s went on their last, ceremonial trip along the Blue Line Thursday morning -- all while decked out in the cars' original exterior decals and featuring interior advertising from 1969, when the cars first debuted.

July 31 was the cars' last official day of regular service, the Chicago Tribune notes.

The cars are most well known for their accordion "blinker"-style doors that pivot inward upon opening, often to the surprise -- and annoyance! -- of passengers standing near the doors.

The cars' farewell means that 100 percent of the agency's rail cars are now accessible to passengers in wheelchairs, CBS Chicago reports -- though about one-third of the CTA's train stations remain inaccessible to wheelchair-reliant riders.

CORRECTION: A previous version of this story stated incorrectly the number CTA rail stations are not accessible to passengers in wheelchairs. This has been updated.
