Wat nu wel duidelijk te zien is, is hoe je professioneel een buitenspoorweg maakt: met zware betonnen elementen die de onderbouw vormen. Hierop worden de rails direct gelegd. Ballast wordt tussen de rails gestort als afwerking.

Yesterday (April 8, 2012) I went to the renewed miniature city of Madurodam (The Hague). To my regret not all exhibits were finished. Not many railway lines were in use. Sligthly disappointing. But enough to see for a small movie

The way to build an outdoor model railway was clearly visible: concrete pre-fab blocks as roadbed. The tracks are directly laid upon the elements. Ballast is put between the tracks as a finish.
