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. While large stations have platform displays with multiple rows, the Deutsche Bahn network operator developed the Dynamic Font Indicator ( (DSA)) standard system for smaller stations with single row. In 2011 a federal funding was granted to equip 4500 additional stations with DSA signage, making for a majority of 6500 DSAs by 2015.
