that has taken place at a large scale for more than a century. It is
an activity that involves large volumes and low profit margins
with shipments being constantly traded. It is not uncommon that
a specific shipment will be traded several times while at
storage facilities and even while in transit, which can involve
rerouting. For countries
such as Canada, grain exports have been a strong factor behind the development
of inland rail networks as well as port terminals. For ports, this mainly
implied the construction of large grain elevator complexes able, through
a system of conveyor belts, to load bulk cargo ships.
