The Transportation Security Administration (TSA) has chosen a rail station in New Carrollton, Md., for a two- to three-month test of a passenger screening system.
The test, which is expected to begin by the end of May, comes in the wake of last month's deadly rail bombings in Madrid.
The rail platform in New Carrollton serves both Amtrak and MARC, a commuter rail system operated by the Maryland Transit Administration.
TSA officials are considering several technologies to use in the screening process. They say the biggest challenge will be to expedite the process so trains can keep to their schedules.
