When the Altenkirchen–Au (Sieg) railway was opened on 1 May of the same year, Altenkirchen station became a transport hub for the Vorderwesterwald (the "forward" Westerwald—meaning close to the Rhine).

After the Second World War, Uerdingen railbuses operated on the line from Engers via Siershahn and Altenkirchen to Au (Sieg).

With the takeover of operations by Vectus Verkehrsgesellschaft on 12 December 2004, the class 628 diesel multiple units, which had operated since 1986, were replaced by modern LINT DMUs and the request stops between Altenkirchen and Au became regular stops again.

Since 2006, Westerwaldbahn GmbH (WEBA) has been serving freight customers by rail on the Selters–Raubach–Altenkirchen route, including a siding in Neitersen and the Schutztankbau company in Selters, where the line runs between the factory buildings.

Regional bus services are mostly operated by the Rhenus-Veniro Group-owned company Martin Becker.
