Notes / Anmerkungen

Tracks and their children are modelled through <trackElementVis> elements referring to their beginning, end, platforms, switches etc. This is because, in a planar space, the line is represented by two dots. In the railML^® world, these two dots are <trackBegin> and <trackEnd> elements. The “x” and “y” coordinates are attributes of the <position> child element.

One can find out whether something is visualized by <trackElementVis> or <objectVis> by finding its position in the Template:Eml hierarchy. Every child of a <track> element is visualized by <trackElementVis>. In that, operation control points are <objectVis> elements. These have not only a <position> child but also a <size> one.
