Large bus stations and hubs have metal detectors. It is probably not very practical to use them at small stops.

The screen door in China looks like this:Screen doors are an excellent idea to keep waiting passengers away from tracks and incoming trains. Here in Canada also there are no screen doors. Whenever I'm waiting for the subway train I make sure that I stand far away from the railway tracks or lean against the wall if I'm near the tracks.
Can you post a picture of screen doors of subway stations in China please?

Hair-Raising Door Glitches Send New Orange Line Trains Back to the Shop
Frequent riders of the MBTA’s Orange Line have noticed that the line’s brand-new vehicles haven’t been around to delight their riders for a few days.
Last night, transit advocate Chris Friend observed that the last time one of the new trains was in service was last Friday afternoon, right around the time this MBTA customer offered this review of the new equipment:
Another rider’s tweet from earlier the same day suggested that this wasn’t a one-off event:
MBTA spokesperson Joe Pesaturo confirmed Wednesday that the new trains had been pulled from service in order to fix the automatic doors.
“As part of the early stages in any procurement process for new rail cars, vehicle engineers closely monitor a train’s performance and identify areas for improvement,” Pesaturo in an email message. “To improve the performance of the cars’ doors, personnel this week are replacing a component with a new one modified by the doors’ manufacturer. The modified door component comes at no cost to the MBTA.”
Pesaturo said that the new trains should be back in service by next Monday.

‘Uncommon Noise’ Pulls New Orange Line Trains From Service, Again
Dec 2, 2019

The MBTA’s new Orange Line trains, which debuted this summer, have been taken out of service indefinitely while engineers investigate an “uncommon noise” coming from the underside of the new trains.
“With safety as a top priority and out of an abundance of caution, the decision was made to temporarily remove the new cars from service to investigate the issue, any potential impacts, and deploy a fix, if needed,” wrote Battison in an email message Monday morning. “We anticipate the issue to be resolved soon with the cars back in service following this investigation, which is currently taking place.”
At a Wednesday press conference, MBTA General Manager Steve Poftak added that, after some testing, MTBA engineers have pinpointed the source of the noise as a wear pad at the location where the trains’ wheel trucks are attached to the body of each car.
Poftak stressed that the MBTA wants to address the issue now, before additional new trains are manufactured and delivered. Under the Orange Line’s new vehicle procurement program, the MBTA expects to take delivery of 152 new Orange Line cars before the end of 2021.
“I’ve repeatedly emphasized to our vehicle engineering team that safety and a durable long life for these cars is a top priority,” said Poftak. “So by catching this issue now we’re able to fix it and not have it occur on the remaining cars… we want to be able to fix this problem now at the earliest stages.”
Poftak declined to estimate when the new cars could be back in service.
According to newtrains.today, a website that monitors data from the MBTA’s real-time vehicle location service, the new Orange Line vehicles haven’t been in service since November 18, the same day that one of the new trains had gone off the rails in the Orange Line’s maintenance and storage facility in Medford:
The new trains also had another extended hiatus from service earlier this fall, when MBTA engineers were forced to fix a glitch that caused its doors to unexpectedly open while the trains were in motion.
The MTBA celebrated the debut of its first new Orange Line train in August, and a second train entered service in September.
Since then, though, the rollout of new trains has stalled, with no new trains entering service in October or November. In order to meet the agency’s goal of replacing all of the Orange Line’s trains by 2022, new 6-car trains would need to enter service roughly every month for the next 24 months.

MBTA Board Update: More Bolster Banes on New Orange Trains
Mar 10, 2020

At the MBTA’s regular Fiscal and Management Control Board meeting yesterday, T officials presented an update on the new Orange Line cars, which have been taken out of service for the third time since they debuted last August.
Employing an idiom that has gained remarkable popularity for cancelling plans this winter, Deputy General Manager Jeff Gonneville told board members that the new trains had been pulled “out of an abundance of caution” after engineers identified another issue with the new trains’ bolster components, which lie between the floor of each car and the truck frame, which holds the train’s wheels (see diagram above).
Readers may recall that the T also pulled the new trains out of service last November after the same parts were determined to be the source of an “uncommon noise” on the new trains.
In a January FMCB meeting, Gonneville reported that those parts had been replaced, and that the assembly line has been updated in the Springfield manufacturing facility where additional new Orange and Red Line trains are being assembled.
But now, the same part appears to be creating a new problem.
“It is not the same issue as we were seeing the last time, but (our engineers) also worked to come up with a retrofit – a modification for a particular part – that we are going to be doing and installing on the vehicles,” said Gonneville on Monday.
“We are planning to do some testing on that part on the cars early this week with the hopes that we begin retrofitting later in the week,” continued Gonnville. “We are not ready to commit when the trains will go back into service, but certainly we are optimistic that they will not be out of service as long as, or much longer than they were last time.”
A July 2016 investigation from FactWire, an independent investigative journalism nonprofit based in Hong Kong, found that similar problems had led Singapore’s transit agency to secretly ship 35 defective trains back to CSR Sifang, a CRRC subsidiary, for complete replacement.
“It’s a structural problem,” an anonymous source from the Chinese rail industry told FactWire. “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.”
MBTA officials declined to respond directly to the FactWire report, but said that the MBTA, CRRC, and other vendors have been collaborating on a new design for the bolster components.
Gonneville assured board members that all future Orange and Red Line cars scheduled to be manufactured by CRRC would also adopt the new design.

The COVID-19 pandemic is adding to project delays in the MBTA’s effort to replace aging subway cars and alleviate crowding on the Orange and Red lines.
The MTBA celebrated the debut of its first new Orange Line train last August, and a second train entered service in September.
In the eight months since then, though, no new trains have arrived, and the new vehicles that have been running have been pulled from service several times to address mechanical problems.
The new Orange and Red Line cars are a key element in the T’s ambitions to reduce crowding on its two busiest subway lines by putting more trains in service and reducing delays from mechanical problems.
The availability of new trains will take on even greater importance if, as anticipated, the economy begins its phased reopening this summer with increased physical distancing requirements on transit vehicles.
At a January board meeting, MBTA officials reported that the line’s third new trainset could enter service “in late February.”
Instead, in early March, at the very beginning of the COVID-19 outbreak, MBTA officials reported that the new trains had been pulled from service again to address ongoing issues with the “bolsters,” which connect the train cars to its wheel assemblies.
The two new trainsets have since re-entered service. Transit advocates have reported sightings of a third new trainset in testing, but those vehicles have yet to open their doors to the public.
The agency has also taken delivery on the first of 252 new Red Line train cars that have been ordered from the same manufacturer: at a press event to show off those new cars in November, T officials said that the first new Red Line trainset could begin rolling this spring.
In response to a press inquiry this morning, MBTA spokesperson Joe Pesaturo wrote in an email that “like almost everything else, the delivery, testing and acceptance processes for new rail cars has been impacted by the pandemic… The MBTA vehicle engineering and operations teams are working closely with the rail car manufacturer to implement measures that allow the procurement process to continue while protecting the health and safety of everyone involved in this complex effort.”
Pesaturo declined to answer a question about whether the manufacturer was still on track to deliver all 140 new Orange Line cars by the end of 2021.
Hes now clearly a mascot for the zionists
Made in China
Those trains are made in USA by a Chinese company, very surprise an American is bashing a USA factory.
MBTA Board Update: More Bolster Banes on New Orange Trains
The Chinese copy the design wholesale and make cosmetic changes to claim it as their own.Made in China, steal IP from other nations, copy from everywhere and then export low quality shitty products. The mantra of the Chinese for decades now, finally the world is waking up, the only product they have made that last a long time is the CCP Virus.
The Chinese copy the design wholesale and make cosmetic changes to claim it as their own.
The problem starts when the specifications change more than marginally , then the lack of design experience emerges.
I have inspected their equipment in China and they try all the tricks in the trade to get it passed.
Basically how close the equipment is to the original design decides how robust the equipment is. If Chinese have made too many changes from the original design, the problems surface.
No idea about the chip you mention. In industry procurement decisions are majorly based on price and sometimes delivery. Chinese are the cheapest producers and since Indian pvt companies are independent, they buy from wherever they find the cheapest stuff. They don't consider lifetime cost of ownership and Indian companies in the power sector faced the quality issues "bigly" a decade back and have now learnt their lessons.So who did Huawei copy the Ascend AI chip from?
How are Indians qualified to inspect Chinese products when India cannot even manufacture many of the said products?
Yah, your source use typical tactics like quite from anonymous Chinese source with no name quote and then self painted story to smear Chinese. I have seen many of these kind use by western media to create unreliable media report on China.Read the red again.The train has design issues not manufacturing issues. The Singapore trains also had similar bolster design issues.

Mainland manufacturer for MTR secretly recalls 35 trains from Singapore due to cracks
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.”

India has a large manufacturing base but is not competitive in price to the Chinese. If price of Chinese is little less , we always buy Indian because of better quality.. But if difference is large , Chinese products are picked up.
Indian presence in the semi conductor business is small. Their is a world outside electronics hardware. No need to reply if u want to only troll .Indian quality... holy shit... I evaluate industrial OEM components all the time. We don't even consider Indian. It doesn't exist. Which Indian company produces microprocessors? LED dies? precision optics? vacuum instruments? chemical equipment? they don't exist. India doesn't have a semiconductor industry, optics industry or semiconductor equipment industry at all.
