Railroads

Railroads offer flat bonus to movement speed between provinces. As distance is evaluated in both trade and spread of bureaucratic control, building roads helps centralize your nation and reduce transportation losses.

Ports

Added in V1.3.1

• Civilian ports are separate from military naval bases and employ unskilled labor to produce port capacity service. Currently ports employ both sailors and actual port workers.
• Naval trade routes purchase port capacity service in order to maintain their size or expand. If the port is profitable, local market pays for its expansion. Profit and loss of the port are accounted as market profit and losses
• Construction of naval bases allows to manually help expansion of the specific port.
• Starting naval bases and population decide the initial size of local ports.
• Port sizes can be seen in a special map mode in the economy scene to see the current size of ports.
