When commuters at Los Angeles’ Union Station came down the escalator this week, they were greeted with a new security measure, ABC News affiliate KABC in Los Angeles reported.
The Los Angeles Metro will become the nation’s first subway system to screen passengers with body scanners, the city announced on Tuesday.
“This new technology will augment our already aggressive safety and security measures and help us proactively deter potential attacks to our system,” Sheila Kuehl, Los Angeles County supervisor and Metro board chair, said in a statement.
The technology, purchased from Thruvision, a United Kingdom-headquartered company, was tested by the TSA at the 7th Street/Metro Center Station over the last year, the TSA said in a statement.
“TSA is pleased to have been a partner during the evaluation and testing process, which ultimately led to the purchase of a recommended system to help detect and deter potential acts of terrorism while keeping the traveling public safe,” TSA Administrator David Pekoske said in a statement.
How the new security system works
Commuters will be scanned for weapons when they walk by the small, mobile machine, KABC reported.
Normally, a person's body produces naturally occurring waves. But when the person is carrying a concealed object, these waves are blocked and detected by these scanners, the TSA said.
"This is a completely noninvasive and portable screening system that passively screens weapons or individuals for weapons or explosive devices," Phillip A. Washington, Metro's CEO, told KABC.
While the training to use these scanners will start immediately, KABC reported, the deployment will roll out across several stations in Los Angeles County over the next few months.
