Via email, Dave Navecky of the National Transportation Surface Board confirmed that there's still no response to its Request for Additional Information sent to the Canaveral Port Authority back in February.
Here's what's interesting, though: His response, below, indicates that his office in the NSTB doesn't want to talk about it any more, and that anybody that wants to know about it can dig for it themselves. This is kind of the same tactic the Canaveral Port Authority has taken on it... by referring people to the NSTB website on the project here rather than cooperating or commenting.
Rest assured, I'll keep looking. But just incase you'd like to dig yourself, here's a click-through version of the link for the all incoming correspondence relating to the Canaveral docket. Although Mr. Navecky wasn't quite forthcoming with instructions, I'd recommend sorting the list by incoming date, then expanding the list... I'm sure there will be more to come, so stay tuned.
Also, for those that feel so inclined, here's a petition relating to the rail project.
