Did some Googling this evening, and came up with some amazing capacity numbers. The Tomorrowland expansion of 1975 (Space Mountain & Carousel of Progress in January '75, and the PeopleMover in July '75) added some truly massive ride capacity to the park that year. It helps that the Carousel Theater and PeopleMover ride systems are the two highest ride capacity systems they've ever built, but still, the Tomorrowland expansion of '75 was truly epic.
Sit down before you read these numbers...
Tomorrowland Expansion 1975 Hourly Capacity
Space Mountain - 1800 riders per hour
Carousel of Progress - 3600 riders per hour
PeopleMover - 4000 riders per hour
Total 1975 Expansion = 9400 riders per hour
Versus what we already know about the Fantasyland Expansion of 2012-14 based on the existing DCA version of Mermaid, the doubling of the current Dumbo capacity, a guesstimate of the mine train, and a subtraction for the closure of Snow White's Scary Adventures.
Fantasyland Expansion 2012-14 Hourly Capacity
Little Mermaid - 2000 riders per hour
Dumbo (the gain of one additional spinner) - 600 riders per hour
Mine Train - 1200 riders per hour
Snow White's Scary Adventures - Subract 700 riders per hour
Total 2012-14 Expansion = 3100 riders per hour
It's roughly one-third the ride capacity they added to Tomorrowland back in '75. Amazing, isn't it? :animwink:
