WMATA Bus/Rail Pick-up Times Online

WMATA may have Metrorail train departure time signs at the entrances to metro stations, but that doesn’t help if you are trying to decide when to leave work or home to make the next train with the least wait.
Into this comes the Metro’s latest techno-gadget: real-time Metrorail and Metrobus information online.
While the Metrobus timing is limited to only a few lines, the Metrorail timing is active for all Metro stations. This is convenient, no more 15 minute waits on the station platform, but I wish you could see where trains are real-time.
The practicality might not be high, but it would have a much greater “wow” factor!
According to outgoing Dan, they considered doing real-time info, but decided against it on security concerns: http://www.wmata.com/chat/transcript.cfm?ChatID=10 (scroll to the second to last question).
I concur. Although completely in the realm of possibility, I highly doubt they would release that kind of real-time information.
