The CTA isn't certain when its new train cars will return to service because of a problem with a weight-bearing part.

The cars were sidelined in November. CTA inspectors found a potential defect in the area that contains the axles and wheels and attaches to the rail car's chassis.

Tests are being done to see if the cars are safe.
