Economy and infrastructure
Brandoberndorf has been since 2000 the end point of the Taunusbahn railway, run as Rhein-Main-Verkehrsverbund line 15 by the Hessische Landesbahn GmbH. It is part of a once abandoned Deutsche Bahn line that now sees new life as a commuter railway. The stretch from Grävenwiesbach to Brandoberndorf was brought back into service in 2000 after the line's great success since 1993, when service began.
