U.S. gov't urges Kawasaki Heavy to inspect carriages over derailment
KYODO NEWS - Oct 20, 2021 - 03:57
U.S. transportation authorities have called on Japanese manufacturer Kawasaki Heavy Industries Ltd. to launch a prompt inspection of its carriages over a recent derailment incident in the Washington subway system.
The Washington Metropolitan Area Transit Authority also suspended the use of Kawasaki Heavy's 7000-series train cars on Monday, saying it will continue subway operations using different carriages until the safety of the type involved in the incident is confirmed.
A train on the Blue Line of the Washington subway system derailed on Oct. 12 with 187 passengers on board. Although no fatalities were reported, a senior official of the National Transportation Safety Board told a press conference that it could have been a major disaster.
The 7000-series carriages have been used in Washington subway operations since 2015. As 748 cars of the type were in use, accounting for roughly 60 percent of the total number of carriages in the system, the suspension has resulted in drastic reductions of services, affecting commuters in the U.S. capital and surrounding areas.
According to the NTSB, the Washington subway operator has been aware of problems associated with the 7000-series since 2017, and has confirmed 39 cases of irregularities linked to the carriages so far this year.
Kawasaki Heavy said on Tuesday it is cooperating with the NTSB and the Washington Metropolitan Area Transit Authority on the matter.
The Japanese heavy machinery maker is also a major provider of subway carriages for New York, with its U.S. subsidiary having received a $3.7 billion order in 2018 to build some 1,600 cars for the New York subway system.

New MBTA Red Line, Orange Line trains to remain out of service
The MBTA’s newest Red and Orange Line trains will remain out of service after an investigation into a March 16 derailment identified “something acting abnormally” within their truck frames, officials said Monday.
MBTA Deputy General Manager Jeff Gonneville said tests conducted on the cars, manufactured by Chinese firm CRRC, determined that as the vehicle mileage increases, it takes more and more force to turn their truck frames.
Investigators are “zeroing in” on components known as side bearer pads, which regulate rotational force on the truck as it moves. As a rough comparison, Gonneville likened the issue to the brake pads on an automobile, though he stressed that investigators have found no brake-specific issues on the subway vehicles.
“As you’re driving your car and as your pads are wearing over time, the way you’re operating and the way your brakes feel and the way your car performs as you’re stopping remain the same,” Gonneville said. “It doesn’t change. Using this same analogy, what would be happening is your car would be gripping harder or stopping faster every time as the pads are wearing, which is not how it is designed.”

Did you read the part about the defective wheelset design?
Driving isn't the problem.

Probably because you never hear about it from your media when a locally found defective train is pulled off the line and simply replaced with another. They don't want the Chinese people to doubt the quality of Chinese goods and reinforce the sterotypical image of China only making second-rate products.
But Meanwhile in other countries the news about problems is published

Try it for every other manufacturer. You'll get the same thing. Like Bombardier:

Most new TTC streetcars to be recalled to fix welding defect, Bombardier says

US government procurement isn't like selling Teslas especially for civil engineering projects directly dealing with the public.
You can't tweet, con and lie your way into a contract with them. You can't say it'll be done in 2 years then in 2 years say the same thing again. People go to jail for less. There's hard audits for literally everything, a paper trail measured in thousands of pages, permits, etc. And that's for a domestic American company. A Chinese company would be subject to 100x more scrutiny.

LoL, Probably is the ticket for you to live in your delusional world. do you know the sheer size of China's railway and subway system? do you know if a subway train had problems they'll be the first thing hit the social media because tens of millions of people take them everyday? grow some brain.

China was pretty quick to bury some of those Wenzhou accident train compartments on site. Videos of wreckage being trucked down the streets didn't sound appealing.
Hasty burial of wreckage sparks suspicion - Chinadaily.com.cn
Beijing - Burying parts of the wreckage from Saturday's deadly high-speed rail accident was a part of the rescue operation and not an attempt to hide evidence, a spokesman for the Ministry of Railways said.
www.chinadaily.com.cn
Authorities said there wasn't any empty areas to temporarily move the trains to during the investigation so they buried them to give investigators space to move around in.

Bringing up an accident which was widely reported 10 years ago only further shows how desparate you are in finding fault with China, Contrary to western lies,that accident was widely discussed on the Chinese social media and everyone knows it in China, and, really? you have to dig out western lies even from 10 years ago? are you kidding me?

Contrary to Western lies??
No, contrary to your lying brain is more like it. You are just saying that to intentionally go on a tangent and avoid the original issue.
I don't recall ANY media saying this incident wasn't reported to the Chinese people. I think your mind is simply making things up again. The Psychology term for what you keep doing is "Confabulation",
If you want to go on your usual tangents please dig proof of your assertion up to prove you are not a perpetual liar. You do this all the time. It's amazing!

We live in China and we know whenever a train malfunction they immediately hit social media top news , Beijing has the world largest subway system and technical malfuctions do happen and result in hours of suspension of services, but they happen extremely rare, millions of people in the city depend on this very reliable network.
Your US rundown railway and subway trains derail regularly, better check yourself for this terrible occurance.
