An all-too-familiar sight at LAX and the rest of the nation’s airports will soon be coming to the city’s busiest train station. KNX 1070′s Pete Demetriou reports rail passengers have started seeing Transportation Security Administration on patrol at Union Station on a more frequent basis. As many as 25 VIPR (Visible Intermodal Prevention & Response) teams began patrolling train stations nationwide last summer conducting an estimated 9,300 “suspicionless” spot searches of travelers. The agency has said the presence of officers with explosive detection dogs, radiation monitors and other devices will act as a deterrent in the nation’s busiest travel hubs.
