The Vienna Airport line shuttle installed outdoor E Ink signage in its stations in Vienna to show real-time passenger information to guide travelers to the airport. The project includes signage for all the shuttle bus stations (over 25).

The two main stations use a large double-sided 32" 2560 x 1440 E Ink displays (shown below), while the rest of the stations show a 15" E Ink display (shown above).

The project was performed by Austria-based Next Urban, which says that it uses the world's first double-sided 32" E Ink displays.
