The Transport Ledger displays sliders showing the amount to be transported this turn of every commodity currently available.

Under some of the sliders you may see a red or green line. A green line means that industry has a demand for that item and the demand is being satisfied by the amount shown on the slider. A red line indicates an unsatisfied demand from industry.

On the lower right of the page is a colored bar showing the total transport capacity (freight cars and barges) you are using and the total you have available. This number is a limit. The total amount shown on all the sliders can never be more than the amount of transport capacity you have.

Hot text in the upper right of the screen helps you identify these displays.
