WBN, KVA Dordrecht, Waddinxveen, Vordere Wasserstellung, Oude Dreef.
Driving from Gouda via the Juliansluis towards Waddinxveen via N456 and then you take the N454. When you are almost in Waddinxveen driving over the Kanaaldijk, you have to go to the left into the Oude Dreef, towards a railroad viaduct.
Most part of the railroad track between Gouda and Waddinxveen was part of the Vordere Wasserstellung because of its structure with heights and waterways.
The "Erste or Vordere Wasserstellung" was a German line about 30-50 km's land inwards behind the dunes to slow down advancing enemy troops. In case of a landing on the Dutch coast and a break trough, they could fall back on this prepared stopping line from Amsterdam-Alphen a/d Rijn-Gouda-Dordrecht-Moerdijk-Roosendaal. The Germans used the technique of inundation, by setting parts of the land underwater about 60cm deep. They also made light defence objects like small gun emplacements, barbed wire lines and mine fields to close the gaps in between.
1x Defensive line.
