One possible problem here: the "of NP" is excluded from need.
A simple extension: follow nmod_of.
More broadly: can take catena: N head, and transitive closure of all its outgoing dependencies. Basically recover NP "constituent".

We may want to extend triggers for @Transport to include one or both of 'shipments' and '[lemma=be] en route to'; which would let us pick up the roles of shipment, origin and destination, if expressed.

It looks like ShipmentOf(x) is something we'll need to identify.
