It's not enough to simply reach land on a planet, you also have to be able to get around on its surface. A robust transit network will allow for greater exploration and colonization of the surface, encouraging more people to immigrate and allowing locals greater access to the frontier.
This transit network greatly increases the population growth in the city it is built in. Because this facility removes biomass, you might have to counteract it by increasing the biomass.
Beginner Mode differs in time needed compared to Normal Mode. The Culture modifiers accounts to the total Biomass, Population, Credits, Research Time and/or Construction Time gained/lost for the buildings/research.
