North America - metro maximum speeds map. Colour-coded permitted speed limits across the subway and rapid transit network — comparable line by line.
North America - maximum permitted operating speed across every metro and subway line. Metro speeds typically range from 60–80 km/h on older systems with tight curves and short station spacing, up to 120–140 km/h on modern automated lines. Fully automated driverless systems — such as Paris Line 14, Dubai Metro, or Copenhagen Metro — often achieve higher average speeds due to more precise acceleration and braking. The speed map enables comparison of operational performance between lines and shows how network investment has evolved over time.
