Discover various transportation methods and how they work
World Number 2 has several means of transportation
The most common one is the highway system. The other one is the road and street network
Each city is connected to at least one via road, but not all are connected via highway
Highways are colored red with a white stripe while roads are solid white
Highways usually flow through the busier cities, while roads connect any city
Navigation icons
can be found at the edges of the towns
They will allow you to travel to the adjacent city, just as long as there is at least one highway or road connection
The second most widely available form of transport is the train system
Not all cities will have it
You can find the train system by looking for this icon 
Hovering over the train icon will display all available destinations from a particular station to another
You can also come across the airport system
Cities with 
icons will have a function airport
You will be able to travel to any other city that also has an airport. They will not have to be adjacent to the current one
Helipads work much the same way and can occasionally be found in the urban and suburban areas
Their destinations are other helipads. Look for the 
icon
Out in the water look out for the 
icon. These will ferries take you to islands and across rivers
Over time, more transit systems will be added
