Infrastructure

Roads
Roads are obviously used by vehicles. Pedestrians also use them to get to buildings like their home or their workplace. Vehicles cannot leave the roads. The only exception are forester trucks in automatic mode. A road connection is required to reach any building.

There are 3 main types of roads. They have different top speeds and different cost. A conctruction office is required to build roads with your own means.
 * dirt roads
 * gravel roads
 * asphalt road

Roads can be upgraded but not downgraded.

Asphalt roads have 4 different forms Dirt roads have no building costs.
 * no sidewalks
 * with sidewalks
 * with sidewalks and streetlights
 * with sidewalks, streetlights and cables for trolley cars

Rail
there are 3 types of rail. A rail construction office is required to build rails. in order to have several trains signaling is required. This can be tricky for unexperienced players.
 * wooden rails, top speed 70km/h
 * concrete rails
 * concrete rails with an electric connection

The system is compareable to many other games involving trains. Examples:
 * transport tycoon/ open ttd
 * mashinky
 * factorio

Electricity (optional)
It can be activated on a new game. Buildings require electricity to function.

At the start you are required to import energy from a neighbour country.

High Voltage (110kV)
high voltage is used to spread large amounts of energy over long distances.

some builings require a high voltage connection like the steel mill or power plant.

a transformer is needed to convert the voltage from 110kV to 22kV

a switch is necessary to connect 3 power lines.

Medium Voltage (22kV)
medium voltage is used to spread energy within a smaller area like a town or industrial area.

there are 3 power lines that support different levels of power. a switch is necessary to connect 3 power lines. Different types cannot be connected directly.
 * small (wood) 0.65 kW
 * medium (wood) 1.2kW
 * large (metall) 2.2kW

Low Voltage
Low voltage requires very little attention. A substation needs to be in range of a building to supply power to it.

An electric substation needs a connection to the medium voltage grid.
