I have a theory.
Notice on that map that FDOT is the corridor owner from rt 528 until rt 536. From there to Tampa, its Brightline as the owner.
The Sunshine corridor proposal has said that SunRail would lease running rights to Brightline over their tracks.
I suspect that this is the way that they have to play it to get the federal funding. It has to go to a government sponsored group, not a private company.
Since Sunshine corridor has stated that it runs to Disney, then Brightline is leasing running rights basically from their maintenance facility at the airport all the way to Disney.
After Disney, Brightline is the owner and paying for construction.
This means:
1. Brightline is saving about 2 Billion dollars on construction costs in building the MCO to Disney segment. No wonder they are excited. Granted, they have to pay yearly running rights, but that is over time, and not all at once. This also explains why they are content with the delay in construction this is causing. Wait several years to save 2 Billion?
2. With all the guaranteed costs that Universal and the I drive group are covering, even more savings.
3. I think that the the feds wouldn't allow the southern end of SunRail to terminate on Disney property. It would have to be a public location. This would also help in the grant justification. They can now claim that the Disney station services the immediate area also. Bringing more customers. Lynx can run routes from the station to local employment corridors getting people to their jobs.
4. It explains why the planning group for the Sunshine corridor included everyone but Disney. The group knew that they couldn't terminate on their property to get the federal grants, so there was no reason to include them. They are basically like any other business in the area. They can get people from the station via Lynx routes or run their own shuttle to the station.
5. This could also explain why Disney seems to be upset. Not because of the Universal stop, but because they lost the stop being on their property.
6. This could also explain what Disney means by the route shifted. In their eyes, it did. It shifted to rt 528 and the sunshine corridor which allows federal grant dollars to pay for it, but requires the Disney station to shift off property.
Just a theory. Feel free to commence ripping it to shreds.
