+
+Update the page $ARGUMENTS to new train category shortcodes.
+
+A shortcode looks like:
+
+```
+{{% train-category
+    title="title"
+    type="highspeed" (can be highspeed, regional, bus, funicular)
+    fip_accepted=true (can be true, false, partially)
+    reservation_required=true (can be true, false, partially)
+    reservation_possible=true (omit the attribute if false or if reservation_required is true)
+    risk_of_confusion=true (previously marked with ℹ️ in the title, omit the attribute if false)
+    important_info=true (if an important highlight is part of the train category, omit the attribute if false)
+%}}
+{{% /train-category %}}
+```
+
+Important information (previously paragraphs that started with ⚠️ in the text) should be changed to an important highlight shortcut (in the same position as the text was before):
+
+```
+{{% highlight important %}}
+{{% /highlight %}}
+```
+
+If there is a risk of confusion (previously marked with ℹ️ in the text), add it as confusion highlight (in the same position the text was before):
+
+```
+{{% highlight confusion %}}
+{{% /highlight %}}
+```
+
+Keep the "**Kosten für Reservierung:**" section.
