When playersreach the Big Town milestoneinCities: Skylines, they get access to a new form of public transportation: the metro. This is a passenger train that can travel along the surface, go underground as a subway, or climb above the ground as an elevated railway. Metro tracks don’t connect to the railroads that go past the edges of the map, but they can connect between different levels.
Of course, the best option for most cities is the underground metro. This lets players overlap the metro infrastructure with existing streets and buildings, so metro stations can fit in convenient locations without having to completely redo the road network. However, setting up a metro system can be tricky for players who don’t fully understand the new parts of theCities: Skylinesinterface.

Building the First Metro Line
First, players should go to the Transport option along the bottom of the interface. The first tab of this menu is for buses, but the second one has all the metro parts.
Players can choose between three station types: on the surface, elevated, or underground. The surface-level station is the cheapest, and the elevated station is the most expensive. The elevated station also takes up just as much space as the surface station, so players should avoid building them and only elevate the metro tracks when needed.

For its part, the underground metro station takes up much less space on the surface. However, it still generates the same noise pollution as the other two stations, so players shouldbe careful about where they place them. In all three cases, the metro station must be placed next to a road.
After placing the first station, place another one at the desired destination. Keep the station’s orientation in mind, because while the surface entrance is a square the underground station is very long and narrow.
Next, create a metro track that connects the two stations. The track starts on the surface level by default, but players can usethe same controls that raise and lower roadsto raise and lower the metro track. On the PC, this defaults to Page Up and Page Down. Metro tracks can’t take sharp corners the way roads can, but the game automatically rounds the edges of tracks even when using the straight track option.
One other thing players should keep in mind is how expensive underground tracks are. A two-way track on the surface costs 80 per cell, but the same length underground is 380 and an elevated line is just 200. Be prepared tospend a lot of moneywhen building a subway.
The last step to building an underground metro line is to create a route. This works the same way as creating a bus route, and it starts by clicking the Metro Line Tool in the construction menu. With the tool active, players can click on a metro station to create a new line, click on a second station to add a stop, and then click on the first station to finish the circuit.
