"Those new cars have struggled with design problems, including issues with doors opening while the new trains were in motion and, more recently, problems with the “bolster” components that connect the train bodies to their wheel assemblies."

The Chinese company making Boston and Chicago’s new subway cars has big problems in Singapore

Dozens of cars are being shipped back to China after cracks appeared in a crucial part of the frame.

"Chinese train manufacturer CSR Sifang has run into serious quality problems in a major project in Singapore

The mainland railway industry source stated that quality issues with the Chinese-made C151A trains began to worsen in 2013. They said cracks were found in structural components, including the sub-floor – a compartment under the passenger floor holding the equipment box and electrical wires – and bolster function parts connecting the car body to the bogie, the latter having the most serious problems. “It’s a structural problem,” said the source. “The bolster function balances the train’s weight and swing range, [therefore] cracks are dynamic, [they] can spread to the train car body with the bolster function, so the entire train car must be replaced.”"

Looks like similar bolster problems all over again.

Singapore too.
The training means to accept 3rd world bumpy rides as the "new normal".

LoL, They all operate very nicely in China, you can only blame yourself for not knowing how to use them.
China operates many railway lines and light rail lines in Africa and South East Asia, US should send their staff to Africa to learn and get trained by the locals there.

Apparently you think Singapore is in the US. We are seeing some of the same problems they had 7 years ago with their Chinese subway trains.

I don't think Africa has any underground 3rd rail subways like the US and Singapore.

Go to Africa and ask them to teach you how to use them, Chinese trains are everywhere. They are not even high speed, you still can't operate them by yourselves...
