An excel spreadsheet for keeping track of cash on hand, income, shares issued and engine level while playing the solo Age of Steam expansion map of Barbados. The final score is calculated after completing 10 turns by deducting $5 per share from the current cash on hand as per the Age of Steam rules for the map. The spreadsheet will give feedback on illegal data (e.g. a goods delivery that exceeds the engine level or a track build that exceeds the current cash on hand) by colouring the offending green input field red and will warn when reducing income to pay expenses by colouring the income field yellow.
