R46 like fiasco averted in Chicago..New CTA train cars had dangerous flaw


Recommended Posts

Check out the story here.

 

"CTA customers worn out by trains that constantly break down and smell like burning rubber might have thought their ride had finally arrived last year when the first new rail cars in decades glided along "L" tracks.

 

But on the underbelly of the new stainless steel cars with fluted sides lurked a threat that was more serious than CTA officials could have imagined when they pulled the cars from service in December.

 

Internally defective and potentially dangerous steel parts from China that could break and lead to a derailment were installed on the cars manufactured for the CTA by Bombardier Transportation, according to the transit agency's internal investigation.

 

The inferior craftsmanship found on the safety-sensitive parts in the rail car truck assembly, which supports much of a train's weight, raises serious questions about Bombardier's quality-control process on the new generation of CTA trains, the investigation found. The CTA is the first transit agency to purchase the cars, known as the 5000 Series. The contract for 706 of those cars totals more than $1 billion.

 

Almost all the steel castings in question, manufactured for Canada-based Bombardier by joint venture partner Sifang foundry in Qingdao, China, were substandard and will be replaced, CTA officials said. Sifang is no longer working on the CTA contract, they added."

It was moved because you posted it on the New York City Subway section. I did not move the post, one of the mods did but here is the appropiate place for this. Hope you understand ;)
