U.S. Testing Rail Travel Security Screening
One by one, the commuters - about 250 of them - paused during evening rush hour yesterday at the New Carrollton commuter rail station to step into a portal the size of a phone booth. There, several cool puffs of air shot at them, enough air to blow neckties into the air. The scene was the launch of a national pilot test program to make rail travel safer. The passengers and nearly 400 bags were screened for explosives at the Prince George's County station- the first such test on a commuter rail system in the country."
