In the second half of the 19th century and until the First World War, the road network, municipal and school buildings were the subject of new developments and, in 1895, the Liège-Plombières railway line with a railway station in Hombourg was inaugurated. On the night of 3-4 August 1914, the army blew up the head of the Laschet tunnel in Homburg. This was the first tangible sign of the First World War in Belgium.
