Metro is considering placing as many as 5,000 LCD or plasma screens that would broadcast real-time customerinformation and advertisements in Metro stations, railcars, buses and bus shelters.

Under the current “Metro Channel” prototype, a third of each 42- to 65-inch screen would be dedicated to Metro customer information, such as train and bus arrival times and service disruptions, and the remaining two-thirds would be allocated to the advertiser’s moving content and to scrolling news headlines.
