also process RIS data. The data can also be queried in real-time via mobile devices like mobile phones. The RIS was started in 2003, and by 2007, it was planned to have 30,000 trains equipped with the necessary train describer (electronic train number). In an accompanying program the older split-flap displays were replaced by electronic dot-matrix signage. Large stations have platform displays with multiple rows, but the Deutsche Bahn network operator developed the Dynamic Font Indicator ( (DSA)) standard system for smaller stations with a single row. In 2011, a federal funding was granted to equip 4500 additional stations with DSA signage, making for most of the 6500 DSAs by 2015. The federal grant came along with a Federal Railway Authority ( (EBA)) order in 2010 to have all stations connected to the travel information system to announce delays with electronic signage or loudspeakers. The Deutsche Bahn operator tried to block that order legally for stations with a very low frequency but lost all lawsuits in 2015. It was given 18 months to equip the remaining stations with DSAs. The DSA system has a GSM radio module to receive a text message to be displayed in a horizontally-moving news ticker style. A loudspeaker may optionally be mounted on top. When there is no delay, the current time is shown statically on its 96×8 LED dot-matrix display. United Kingdom National Rail stations are equipped with visual platform displays and audio announcements, which indicate the next service or services from the platform and warn passengers to stand clear of trains that are not scheduled to stop, not in use or are about to depart. Additionally, concourses and ticket offices have large screen displays that show all of the services available at the station for the next hour or more and, at major stations, the full route of the service and any restrictions applicable (e.g. ticket types, catering services, bicycle carriage). Many smaller and less well-used railway stations have, instead of such systems, "passenger help points", which connect the user by telephone to a control room by pressing an "Information" button. The information is available online at National Rail and on mobile devices. Most London Underground stations have “countdown” displays on each platform. They are simpler than the national rail displays since most platforms serves only a single line, and there are few or no variations in carriage restrictions and destinations served. Audio
