Theoretical hourly capacity
The industry’s basic yardstick is the theoretical hourly ride capacity: how many people a ride could carry in an hour if the queue never ran dry and every seat were filled. One departure every (ride time + loading time) seconds, times the seats per departure: capacity = seats × 3600 / (ride time + loading).
A carousel with 12 seats, a 24-second ride and 4 seconds of loading carries 12 × 3600 / 28 ≈ 1,540 riders an hour. Real rides do worse (empty seats, a slow group, a restraint that won’t click), so parks plan with a lower operating capacity.
More trains, shorter waits
A coaster can run several trains at once, as long as block brakes keep them apart. The next train loads while the last one is out on the track, so departures come more often, but never faster than a train can be loaded: two trains on a 60-second circuit with 20 seconds of loading leave every 40 seconds, not every 30.
How long is the wait?
The guest joining the back of a queue waits for every departure ahead of them: the people in front, divided by the seats per departure, rounded up, times the time between departures. 300 people in front of a 24-seat ride that leaves every 40 seconds is 13 departures, a bit under 9 minutes.
How long a wait feels is another matter. David Maister’s classic 1985 essay on waiting lines argues that occupied time feels shorter than empty time, and that uncertain, unexplained and unfair waits feel longer than known, explained and fair ones: one reason parks theme their queues, show videos and post wait times.
In Park Baron
Every ride window has a Stations or Operate tab with its riders per hour and the wait for the current queue, previewed before you change a setting. Guests have patience: a line that barely moves makes them give up and leave unhappy, and queue TVs and entertainers make the wait feel shorter. Longer rides please guests up to a point but carry fewer riders an hour.
