I can't help but think about how SunRail would have been a great name for (non-express) regional rail service, or even for the HSR system if it had been built back at the beginning of the last decade instead of the beginning of this one. I suppose ultimately Brightline service connecting all of these smaller stations will just be given a name under that umbrella, but still.
Whenever we get around to commuter rail in Jacksonville, I wonder what kind of name we'll give that. First Coast Flyer was a good name, but obviously that's BRT. First Coast Commuter Rail kinda stinks, but then again we actually went ahead with "Jacksonville Regional Transportation Center" when Pond even offered JAXIS, so chances are it'll be that. Maybe "First Coast Connector" if we're feeling good.
To get back on topic, as I said, it looks like the line follows 417 and 536 before breaking off at I-4 and putting the stop in the vicinity of Typhoon Lagoon and Team Disney. A spur seems to be what they've set themselves up for, which I guess isn't completely out there if they ultimately want Tampa-Orlando to be more direct. Looking at the area, it's either going to be tucked up against the highway like at the airport or elevated in the middle like the old HSR proposal. That leads me to wonder if they'd build this new line to true HSR standards (186+) to try and make it easier for them down the road, in the event they want to electrify and upgrade trainsets.
Lake, I would think part of the deal is also giving SunRail access to Disney, which they almost certainly wouldn't build themselves. I imagine there will definitely be a Miami-Orlando express, and perhaps even a PortMiami-Orlando or Disney express.
