+[NOTE]
+Note that this and the following examples in this section use a quantified relationship `-[:LINK]-\+`, which is composed of a relationship pattern `-[:LINK]-` and a postfix quantifier `+`.
 The relationship pattern is only concerned with following relationships with type `LINK`, and will otherwise traverse any node along the way.
 There is no arrowhead `<` or `>` on the relationship pattern, allowing the pattern to match relationships going in either direction.
 This represents the fact that trains can go in both directions along the `LINK` relationships between Stations.
