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 legally prevent that order for stations with very low frequency but lost all lawsuits in 2015. It was given 18 months to equip the remaining stations, which was done 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's no delay the current time is shown statically on its 96×8 LED dot-matrix display.
