Good point, these were built in 1970 and hollow beams were not exactly standard order back then, but then again I tend to doubt that any concrete prefab beams were available back then. And yes, I know that footings are pretty big down there, but I am not sure about 30ft square - not unless they were designed for someother kind of much heavier load. Ever try comparing it to a roadway?
As far as the hub concept that i am thinking of, you would put the hub just west of Epcot. From here you already have most of the monorail built to MK and Epcot - you just have to reconfigure the TTC so that the Epcot beam goes all the way to the MK. That ur upgrade the switch and run both lines off of it. You would then need one line to Studios, one to AK, and one to Downtown Disney. I have to make up another map in something and I will post it.
Now, back to Tyler. While I am impressed by his knowledge and experience driving the monorails and busses, he is NOT a transportation planner. And there are some serious issues with his numbers. First, 27 monorails is quite a huge number. You would not need any more to service Magic Kingdom NOR Epcot. So that means only to Animal Kingdom and Downtown Disney. And with a hub concept you get better utilization rates for them, too. Secondly, $17m for a train - where is this number from? I would love to see some price comparissons on this - I believe that Hitachi is doing a much betteer price on them, and provide a better product to boot.
Now what about Busses? Don't they need service and roadways too? Has anyone bothered to figure out how much the roadways cost? A Bombardier monorail has a cruch capacity about 380, where as the new Nova nusses (all I could find stats for) has a crush capacity of 80. That means you need 4 and a half busses to repalce one monorail. Not to mention the high gas costs, and the fact that you need a driver for each one. Oh, and the Hitachi Monorails have a crush load of 400, and can be coupled together.
As far as the support infrastructure such as stations, there is no difference between that and a bus. It all depends upon how fancy you build it. There is no reason the monorail stations cannot be as simple as the bus stations.
Look, if Busses were such a great alternative to every other transportation system out there, then nobody would be building things like Light Rail. But now suddenly everyone has discovered how expensive all these Bus Rapit Transit systems are in the long term and they are quickly changing over to light rail. Guess what - there is a lot more to a bus than just the vehicle. It is by nature more complex, requiring more service and maintenance. It requires roadways (look at how big the roads in WDW have to be to support the extra traffic), they require extensive handling facilities due to the large number of busses needed, and they use up a lot of fuel and have a high cost for operational personnel.
There are what - 15 bus resorts? even if you ran just one bus between each attraction, thats 75 busses. If you only ran one bus to a hub, you have cut that number by one fifth.
Hey, yeah busses are neat. But they aren't the be all end all.
