A rollsign or roll sign is a mechanical display used to indicate the destination of a bus or train. They are commonly seen in older city buses, streetcars and subway cars, which run on a variety of fixed routes. More modern equipment typically substitutes digital displays for rollsigns, but the long life of these vehicles ensures that many systems still use the devices.
