From there, the line passed by Mill, Peel along the Zuid-Willemsvaart until the Belgium border nearby Weert.

The line could profit from the natural protection of the swamps, rivers and canals in the area.

The railway bridge on the Defensiekanaal near Mill, also had a spargel-obstruction (precursor of the Rommelspargel which the German Army used from 1943 onwards).

The stretch between Griendtsveen and De Peel Air Base and the spot nearby Mill features several visible remains.

The fortifications and the casemates in the municipalities of Deurne, Venray and Mill en Sint Hubert are protected as national monuments.
