Washington, DC's WMATA believes that if they change the names of some of the stations it will make it easier for the public to use the transit system. As a matter of fact, they are so sure of this that they are considering spending the $100,000 per station necessary to change the signage and maps in every one of the 19 stations in the system.
The Metro Board is having some problems with the change however; there are communities and organizations that want their name to be the one used (like some are now, i.e. Bethesda, U Street, Pentagon, etc.) but that is causing some issues; the Board wants the names limited to 19 characters. This will keep names like Ronald Reagan Washington National Airport off the station's signs, and they cannot shorten it because it's a federal law that the name be completely spelled out on any sign.
The Metro Board will be taking public comment on this issue on Thursday November 3rd.
