The Washington Metropolitan Area Transit Authority has bought a pair of Segway-like three-wheelers for its police force.
It's also released a video showing the units in action.
The trikes, which have a top speed of 25 mph, are initially going to work the New Carrolton (Va.) station, where there have been some problems with car thefts and robberies in the parking lot.
Metro officials say they elevated position of the officer gives him a her a good view of potential problems around the lots.
The units cost about $10,000 each and more may follow.
