Herbesthal Train Station, Belgium/Germany frontier, 1918-1919 Herbesthal railway station was the Prussian/German frontier station on the main railway from Germany into Belgium between 1843 and 1920. It opened to rail traffic on 15 October 1843 and was thereby the oldest railway station frontier crossing in the world. It lost its border status on 10 January 1920, however, as a result of changes mandated in the Treaty of Versailles, which left Herbesthal more than 10 km inside Belgium.
