I wonder how much of it is connection fees. For instance, MCO. They aren't getting a stop for free. Will Disney/LBV be connected? While not "publicly funded", I wonder if the Cities of Miami, Fort Lauderdale, and Palm Beach are paying indirectly to have a stop on the line?
Finally, they are touting Miami to Orlando in 3 hours. That's pretty darn good. And considering the intracity traffic between the two, it could be quite a hit.
And $2.5Bn for this much rail is nothing. What IS something is the amount of eggs in just one basket (basically one PE group and its subsidiaries essentially making a bet on the quite risky and ever volatile in every which way State of Florida). FECI could be by far the largest investment in one of FIG's funds (and subsequently this could jeopardize their investment in FECI, or it could be a boon).
To put things in perspective, here in CA, more specifically the Bay Area, just to electrify our existing commuter rail line is projected to cost over $2Bn (that is right now all trains are pulled by DMUs, but they need to electrify the system to expand capacity and allow for CA HSR). Just to build a transit center in DT SF to accomodate an electrified Caltrain underground and potentially CA HSR, and buses, with a park on top, is costing $4.5 Bn. A 1.7 mile underground extension of Muni Metro here in SF is costing $1.6Bn (that is one billion dollars per mile). CA HSR is projected to cost $65+ Bn. The Eastern span of the Bay Bridge was replaced for $6.4 Bn. A new BRT line down Van Ness (just 2-3 miles worth) will cost $125M.
So all in all, that is $14.7 Bn for a BRT route, 1.7 miles of LRT subway, electrification of an existing commuter rail line, a central transit center that only includes 2 modes, and half of a bridge.
So rail around the entire state of FL for a few billy is pretty pretty good!
