Using the Subway efficiently might be premature, souse your development points carefullyto address other essential needs during this period.

Local transportation starts with buses as your city grows. You then bring in trams, offering a flexible alternative for citizens compared to buses. As your city expands further, you recognize theneed for a high-capacity local transport option. This iswhere the Subway becomes an excellent choice, saving time and space without causing disruptions to road traffic.
To use the Subway, start byunlocking the initial tier node, the train, for one development point,and the second tier node, the tram, for two development pointsin the transportation development treewithin theprogression menu. Once these nodes are unlocked, you can accessthe Subway as a third tier node by spending four development points.

How To Set Up The Subway
When deciding to expand your transport network by setting up a subway, there are multiple steps to take, starting fromestablishing the Subway Yard to connecting subway lines.
How To Set Up Subway Yard
The Subway Yard acts as the central hubfor the entire subway system, serving as amaintenance facility and housing all subway-related staff facilities. Setting up the Subway Yard incurs a cost of 200,000, with a monthly upkeep of 48,000.
Upon establishing a Subway Yard, you will beequipped with ten vehicles. If you wish to increase the number withmore five vehicles, you can do it by addingExtra Tracksas an upgrade to the Subway Yard. This upgrade comes with a cost of 75,000, with a monthly upkeep of 16,000.

Another upgrade available toreduce maintenance duration is the Maintenance Hall. This enhancement comes with a cost of 50,000 and a monthly upkeep of 34,000.
Keep in mind that for additional upgrades, you willneed more space beside the Subway Yard.

How To Set Up Subway Stations
You have two choices for building the subway station,underground or overground. Given our priority forspace-saving, the best option is the underground station, which allows for seamless integration between buildings in the city. However,the overground station remains a suitable choice, especially in the outskirts of cities.
The underground station incurs a cost of 50,000, while the overground option comes with a cost of 25,000. Both options have a monthly upkeep of 10,000.

Additionally, there’s an available upgrade toadd servicesfor a cost of 15,000, with a monthly upkeep of 16,000. This upgrade is valuable as itenhances the attractiveness of the station.
How To Set Up Subway Tracks
After completing the setup of allsubway stationsin your city, the next step is toconnect them using subway tracks. Additionally, you need to establishconnections between the tracks and the subway yardto enable the creation of subway lines that link these stations.
For subway tracks, similar to trains, you have two options;one-way tracks and double tracks. The double track incurs a cost of 2,500 for each kilometer, with a monthly upkeep of 250 per kilometer. On the other hand, the one-way track requires half of the cost of the double track.

The double subway track allows for tracks in both directionsfor the subway. On the other hand,the one-way trackcan serve as a means toconnect the subway yard with other tracksor function as atransfer point for tracks.
To establish the underground tracks without any issues, ensure that you setthe elevation at around minus 30 meters. Whilekeeping an eye on pipes and underground cables.
How To Connect Subway Lines
Using thesubway line tool, you may easily establish a line connecting all subway stations. Simplyclick on add a new waypointat each station andcreate a loop that connects all subway stations, making it accessible for all citizens. Ensure that youlink the double tracks to create a line in both directions.
Following this process, you’ll be ready to receive subway vehicles from the subway yard to operate on the newly created subway line.
How To Manage Subway Lines
