Find your metro journey

Metro operations & economics

Experiment with fleet size, service intervals and demand. Learn how metro capacity, reliability, operating costs, fares and public support connect.

What you can explore

Service frequency

A train has just left. How long until the next one? Service intervals depend on both the available fleet and the time each train needs to complete a service circuit.

Capacity and demand

Can everyone board when many people arrive together? People stay in the queue when a train is full. The diorama and its readouts share the same passenger counts.

Reliability

One train spends longer at C. Following trains must retain their separation and may wait outside a station. Their actual positions determine how the disruption spreads.

The cost of a journey

Every service needs electricity, people, cleaning and maintenance. The readouts add illustrative hourly costs for regular operation; frequency changes the resources required.

Fares and public value

A fare contributes to funding and is also a passenger expense. Explore fares, public support and reference income to see the service budget alongside personal travel spending.
