Posted by appohsmit on Mon Feb 14 10:57:36 2005, in response to Re: Off Hours Trains Stop Here, posted by Rail Blue on Mon Feb 14 08:18:16 2005. The original WMATA design specification had the platform edge lights blink where the train was going to stop. (Instead of all the edge lights blinking, like it works now.) The logic for this function was installed in all train control rooms, but the wiring for blinking individual segments was never installed. It will (after 30 years) be finally removed from the design standards soon. |
