Real time train location map

Real time train location map

The data stream used to generate the map comes from the WMATA ROCS (Rail Operations Computer System). This data stream is the same data stream used to display the next train arrival time on the PIDS (Passenger Information Display System) displays in the stations and on the web at wmata.com/mobile/nexttrain. It is also the same data stream used to display the maps on the computes in the station managers kiosks.

Mouse over circle displays station name. Lettered pins shows train approximate location and terminal destination. Mouse over lettered pins displays station name arrival time.

Given the internal fights over letting even the Station Managers know where the trains are located; I'm surprised about this.

As I heard, the arguments sound like the scene from Dr. Strangelove:

General "Buck" Turgidson: Sir, you can't let him in here. He'll see everything. He'll see the big board!

Some Suits were saying the positions of consists should be sekret, as if no one with eyes or ears could ever spot one...
