how fast does the metro go

Metro trains typically have a maximum speed ranging from about 80 km/h (50 mph) to 100 km/h (62 mph) depending on the city and system. The average operational speeds, considering stops, generally fall around 28 to 40 km/h (17 to 25 mph). For example, the Copenhagen Metro has a maximum speed of 80 km/h and an average speed of around 40 km/h with stops included. Washington Metro has a top speed of 75 mph (121 km/h) and an average speed of about 33 mph (53 km/h) including stops. Some fast metros can reach around 100 km/h as a maximum speed but their average speed remains lower due to frequent stops and acceleration/deceleration constraints.
