Industry Giant

Tip: Unless your scenario terrain won't permit it, always start up a transportation network with trains rather than trucks. They're faster and carry more. 
Tip: Place your factories with long-range considerations in mind, straddling several metropolitan areas. 
Tip: Placing a store right next to an identical one owned by the competition can mean you share up to 90 percent of their customers. 
Tip: Use the info icon regularly to view your opponents' product pricing. You can undercut them; they can also deliberately set out to undercut you. 
Tip: Tunnels and bridges will reduce travel costs and delivery lag. 
Tip: Upgrade your transportation network whenever airports and docks become available.
