One of the biggest crime problems in the Metro system has long been thefts from autos parked in the lots at the end of the different rail lines. Thieves know that Metro’s large, outer parking lots are filled with cars whose owners won’t return until the end of the day, so they prowl them like kids in a candy store.

Enter the T3, Metro’s newest experiment in increasing their police officers’ ability to patrol the expansive parking lots. Not to be confused with that other T3, these are $10,000 three-wheeled vehicles that work a lot like Segways, except with slightly more power. WMATA has just purchased two T3’s, which can travel up to 25 miles per hour, and say they will purchase more if Transit Police officers decide they are helpful enough.
