Hi Oliver,
it should be the path property, in your case ont:LocationID. The IRI http://semantic.com/x-org-my-ontology/MyStation-hasLocationID is an (probably automatically created) identifier within you SHACL shapes to say that the node shape MyStation has an associated property shape for a property with the name has location ID. See also the SHACL spec on property shapes for more details.
Best regards
Lars
