Central Places and Transport Places
A distinction exists between cities as central places from those that develop as transport places. The conventional perspective of a city is as a central place that provides goods and services to a surrounding area as well as acting as a consumption market for the resources produced. Transport places do not specialize in serving a surrounding catchment area. Instead, they emerged primarily due to an accessible location along transport corridors. The predominant types of transport places were located along railway lines or along the coastline (or a river). Once goods have been traded over long distances, they need to be broken down for final distribution to the local market. Inversely, for exports, goods or resources need to be collected. This is why load consolidation or deconsolidation is a major function of transport places.
