also designated as Line 43 of the Rhine-Main Transport Association, running from Erndtebrück in Siegen-Wittgenstein district to the town of Marburg by way of Bad Laasphe and Biedenkopf and serving the Dautphetal stations of Wilhelmshütte (Lahn), Friedendorf (Lahn) and Buchenau (Lahn). The last two named stations are conveniently placed for the Hesse cross-country bicycle path (Hessischer Radfernweg) R 2. On weekdays there are 21 journeys between 5:30 and 21:00, on Saturdays 13 between 6:45 and 19:00 and on Sundays 12 between 8:45 and 19:00. All trains allow bicycles. In Marburg are connections to DB's long-distance rail network. Air transport The immediate vicinity has two special airfields at Bad Endbach-Bottenhorn and Eschenburg-Hirzenhain as well as a commercial airfield at Cölbe-Schönstadt. The nearest greater airport is Frankfurt International Airport at Frankfurt am Main. Bicycle and hiking trails Owing to its advantageous location in a low mountain range and its attendant great forests and idyllic dales, the whole region is endowed with a substantial trail network. Its potential, however, was only recognized a few years ago and has been organizationally supported for a short time by the association Lahn-Dill-Bergland e. V. Public institutions Friedensdorf has since the 1950s been the site of an electrical substation. There, high-voltage current at 110 kV is stepped down to the middle voltage of 20 kV. After the transformers' useful working life had come to an end, a 20 kV switchgear set and new open-air transformer fields were installed in 1998. The substation is run by E.ON Mitte. Education In each of the bigger centres in the community is found a kindergarten. Only Damshausen, Elmshausen and Silberg do not have their own. Holzhausen and Buchenau each also have a primary school, the latter's having had until 2006 an attached orientation programme (Förderstufe) which was discontinued because the class-size threshold was no longer being met. In Friedensdorf, alongside the Dautphetalschule with its primary school and Hauptschule and Realschule branch, itself with an orientation programme, there is the Burgbergschule, a school for learning and educational help. A school for the educable mentally handicapped with a department for those who also have physical handicaps is located in Hommertshausen. In Wilhelmshütte is found the Jule-Spannagel-Schule for hard to educate youth. Further schooling such as vocational schools and colleges (or the like) or professional Gymnasien are to be found in the surrounding towns of Marburg, Biedenkopf, Bad Laasphe or Gladenbach.
