What is the difference between carrier assets and carrier infrastructure?

Carrier infrastructure refers specifically to the fixed physical network — depots, sorting hubs, and regional facilities. Carrier assets is the broader term covering infrastructure, rolling stock, loading equipment, and technology systems. A carrier's depot infrastructure is a subset of its total asset base. When assessing European lane coverage, depot infrastructure determines where a carrier runs direct owned-asset operations; rolling stock volume determines how frequently those lanes run and how much capacity is available per departure.
