The world map is dotted with both industries and towns. Cargo for transportation is supplied by both industries (e.g. the coal mine which produces coal) and towns (which produce passengers and mail) and accepted by other industries and/or towns according to their needs (e.g., the power station accepts coal). Placing a station near a source and a receiver of a certain cargo allows transportation between the two. The amount of cargo supplied by a town or industry depends on the quality of transport players provide to move its goods. Payment for delivering cargo depends on the quantity of cargo delivered, how fast it was delivered and how perishable it is. Some cargoes (e.g., passengers) must be delivered faster than others (e.g., coal) to earn a good income.
