United States, Dec 19: An Amtrak passenger train traveling on a new route for the first time derailed Monday in Washington state, killing at least three people as cars plunged off a bridge onto a busy highway at the height of morning rush hour, officials said.

The train, which was carrying 77 passengers and seven crew, derailed in DuPont about halfway between Tacoma and the state capital Olympia on a curve that passes over busy Interstate 5 at about 7:40 am (1540 GMT).

Pictures from the scene showed one Amtrak train car overturned and crushed on the interstate highway and others dangling from the overpass.

Several other carriages of the 14-car train also ended up on the highway, shutting down a key section of the busy artery that connects the greater Seattle metropolitan area to Olympia. All but one car jumped the tracks.

A spokeswoman for Washington State police, Brooke Bova, confirmed the death toll, adding that all train cars had been searched by emergency personnel.

But she cautioned that several of the roughly 100 people taken to area hospitals were in critical condition.

"We don't know if that number will change," Bova said of the death toll.

Officials gave no reason for the derailment of southbound Amtrak train 501, the inaugural run of a new service that promised faster connections between Seattle and Portland, Oregon.

Local officials had warned only weeks ago that the track still might not be safe enough to handle trains at higher speeds.

None of the people in vehicles traveling on the highway below the train were killed, according to Ed Troyer, a spokesman for the Pierce County Sheriff's Department.

Police said five vehicles and two trucks were hit on the highway.

The National Transportation Safety Board has sent a team of experts to investigate the incident.

Chris Karnes, a local transit official who was aboard the train, told local CBS News affiliate KIRO-TV that the accident took place while it was going around a curve.

"All of a sudden, we felt this rocking and creaking noise, and it felt like we were heading down a hill," he said.

"The next thing we know, we're being slammed into the front of our seats, windows are breaking, we stop, and there's water gushing out of the train. People were screaming."

A conductor in one of the two engines on the train placed the emergency call.

"Amtrak 501, emergency emergency emergency, we are on the ground," he said, according to an audio recording of the call.

"We were coming around the corner to take the bridge over I-5 there right north of Nisqually and we went on the ground.

"We got cars everywhere and down onto the highway," he said.

Amtrak president and co-chief executive Richard Anderson said he was "deeply saddened" by the crash.

"We will do everything in our power to support our passengers and crew and their families," Anderson said.

The accident marred the launch of faster services on the route after a $181 million upgrade project that included improving the rails, the signaling technology and the locomotives.

Local officials had worried about trains going at higher speeds through the curves in the area. The trains were expected to reach speeds of 79 miles (127 kilometers) per hour through the densely populated area with the improved systems and track.

In early December, Don Anderson -- the mayor of Lakewood, Washington, a Tacoma suburb just a few miles from the accident site -- had warned that more needed to be done to ensure safety on the route.

"Come back when there is that accident, and try to justify not putting in those safety enhancements," he said, according to KOMO News.

Karnes said the tracks were supposed to have been upgraded to accommodate higher speeds.

"I'm not sure what happened," he said.

US President Donald Trump said the accident underscored the need to invest in infrastructure.

"Seven trillion dollars spent in the Middle East while our roads, bridges, tunnels, railways (and more) crumble! Not for long!" he tweeted.

The new Siemens Charger locomotives were equipped with "positive train control" safety systems, designed to automatically stop the train in dangerous situations and mandated for trains around the country.

But the technology was only expected to be used next year when it is activated on the entire rail corridor, according to the Washington State Department of Transportation.

In 2015, an Amtrak train going far over the designated speed for a stretch of curves in the track in Philadelphia derailed, killing eight.

At the time, analysts said positive train control technology could have prevented the accident.

London, May 20: The current physical distancing guidelines of 6 feet may be insufficient to prevent COVID-19 transmission, according to a study which says a mild cough in low wind speeds can propel saliva droplets by as much as 18 feet.

Researchers, including those from the University of Nicosia in Cyprus, said a good baseline for studying the airborne transmission of viruses, like the one behind the COVID-19 pandemic, is a deeper understanding of how particles travel through the air when people cough.

In the study, published in the journal Physics of Fluids, they said even with a slight breeze of about four kilometres per hour (kph), saliva travels 18 feet in 5 seconds.

"The droplet cloud will affect both adults and children of different heights," said study co-author Dimitris Drikakis from the University of Nicosia.

According to the scientists, shorter adults and children could be at higher risk if they are located within the trajectory of the saliva droplets.

They said saliva is a complex fluid, which travels suspended in a bulk of surrounding air released by a cough, adding that many factors affect how saliva droplets travel in the air.

These factors, the study noted, include the size and number of droplets, how they interact with one another and the surrounding air as they disperse and evaporate, how heat and mass are transferred, and the humidity and temperature of the surrounding air.

In the study, the scientists created a computer simulation to examine the state of every saliva droplet moving through the air in front of a coughing person.

The model considered the effects of humidity, dispersion force, interactions of molecules of saliva and air, and how the droplets change from liquid to vapour and evaporate, along with a grid representing the space in front of a coughing person.

Each grid, the scientists said, holds information about variables like pressure, fluid velocity, temperature, droplet mass, and droplet position.

The study analysed the fates of nearly 1,008 simulated saliva droplets, and solved as many as 3.7 million equations.

"The purpose of the mathematical modelling and simulation is to take into account all the real coupling or interaction mechanisms that may take place between the main bulk fluid flow and the saliva droplets, and between the saliva droplets themselves," explained Talib Dbouk, another co-author of the study.

However, the researchers added that further studies are needed to determine the effect of ground surface temperature on the behaviour of saliva in air.

They also believe that indoor environments, especially ones with air conditioning, may significantly affect the particle movement through air.

This work is important since it concerns safety distance guidelines, and advances the understanding of the transmission of airborne diseases, Drikakis said.

Wuhan, Feb 23: Ninety-seven more people died in China due to coronavirus, taking the death toll to 2,442, officials said on Sunday, as a team of WHO experts visited the worst-affected Wuhan city in Hubei province.

By the end of Saturday, a total of 2,442 people had died of the disease and 76,936 confirmed cases of novel coronavirus infection had been reported in 31 provincial-level regions, China's National Health Commission (NHC) said in its daily update on Sunday.

Ninety-six deaths were reported from Hubei province and one from Guangdong province on Saturday besides 648 new confirmed cases of coronavirus infections, it said.

Hubei province, where the virus first emerged in December last, reported 630 new confirmed cases, taking the total confirmed cases in the hard-hit province to 64,084, state-run Xinhua news agency reported.

The NHC also said China's daily number of newly cured and discharged novel coronavirus patients has surpassed that of new confirmed infections for the fifth consecutive day, indicating that cases of infections are coming down.

Saturday saw 2,230 people walk out of hospital after recovery, much higher than the number of the same day's new confirmed infections, which was 648, Xinhua reported.

A total of 22,888 patients infected with the novel coronavirus had been discharged from hospital after recovery by the end of Saturday, NHC said.

Meanwhile, a team of public health experts from the World Health Organisation (WHO) visited Wuhan on Saturday to conduct a detailed probe about the virus which reportedly originated from a seafood market in the city in December last year.

The NHC said WHO experts along with their Chinese counterparts who formed a joint investigation team have held talks with the local health authority in Wuhan and visited relevant healthcare institutions.

The UN team comprises specialists from the United States, Germany, Japan, Nigeria, Russia, Singapore and South Korea, Hong-Kong based South China Morning Post reported.

The 12-member team, which arrived in China on Monday, was initially designated to visit only Beijing, Guangdong and Sichuan provinces, while the worst-affected Hubei province and its capital Wuhan were missing from the list.

However, the team was finally given permission to visit Wuhan by the Chinese government.

Besides controlling the spread of the virus, a major task for the WHO team along with their Chinese counterparts was to come up with standard medicine to cure the disease.

The NHC said on Saturday that the team had met top Chinese respiratory disease expert Zhong Nanshan in Guangdong, and visited the centre for disease control and prevention in Guangdong and the city of Shenzhen, and Sichuan.

The specialists also discussed quarantine measures, the wild animal trade and community prevention measures with their Chinese counterparts, it said.
