Commuter rail necessarily involves a lot of moving parts. When a key part is dangerous and defective, however, safety can be compromised - raising the risk of a CTA accident.
Last December, the Chicago Transit Agency pulled from service new rail cars with fluted sides that were to have operated on L tracks. The undersides of these cars contained steel parts made in China that were so poorly made that they could have broken and caused a derailment.
A subsequent investigation raised questions about the quality control process used by Bombardier, the Canada-based company that manufactured the trains for the CTA. CTA officials acknowledged that nearly all of the steel castings that were manufactured for Bombardier by its joint venture partner in China were substandard.
The CTA believes the problem has been located, however, and was limited to a particular factory in China. There was "an unacceptably high level of failure at that one factory," said a CTA spokeswoman.
