August 8, 2013 (FOREST PARK, Ill.) --It's the end of an era for riders of the CTA's Blue Line. The agency is retiring the old bi-fold door train cars that have been used on that line since 1969.
The last train using the old cars made its final run from O'Hare to Forest Park Thursday. It was even decorated with classic decals for the occasion.
The CTA is replacing the cars with upgraded models.
