In WitW Ports and Railyards produce capacity points dependent on their size. The points in each location are shown in F2/F3 Modes. 1 capacity point = ability to handle 1000T.
When you load or unload a unit the amount of points consumed is equivalent to the load cost of the unit. But not only that - the more points remaining at a location the less the cost to the unit in SMPs. This reflects the fact that loading or unloading is quicker in a larger port or railyard.
Obviously you can only transfer to and from sea movement in a port. Rail movement has no restriction but the further you load/unload from a railyard the greater the cost. In addition the more you use a rail line in a hex the greater the cost in SMPs to transit the hex by up to x7.
Any rail or port capacity you use for strategic movement is not available for the movement of freight in the automatic logistics phase so as a player you need to consider carefully the use of strategic movement when supplies are tight.
Finally you'll be glad that units in WitW get 200 SMPs/Turn. The screenshot shows rail movement mode so you can see railyards and their points and the colour coding of the rails showing congestion from bright green SE of Amiens with no use to red NW of Rouen with maximum congestion.
Early release, please!!!
