Beginning in 1794, Ediger and Eller lay under French rule and were merged to form a single municipality. In 1815 they were assigned to the Kingdom of Prussia at the Congress of Vienna, and once again became two separate municipalities. Since 1877, Eller has lain near the end of the "Kaiser-Wilhelm-Tunnel", which begins in Cochem and is named after Emperor Wilhelm I (not his more infamous grandson, Wilhelm II). From the time of its completion until 1987, it was Germany's longest railway tunnel at 4 205 m. The tunnel is part of the "Moselstrecke" (Moselle line). Not far from the tunnel portal, and before the Moselle bridge, stands Ediger-Eller railway station.
