Implies that the $79/$149 fares will be increasing?
I don't think it implies it at all. I think it's blunt. These are "starting" and "introductory" prices. They'll adjust as market allows.

My interpretation is that they'll "pin" the fares to 79/149 for a little while at the start, but those will just be the "base" fares longer-term and higher "buckets" will come into play.
Millions of dollars and years overdue for 8 miles of existing track and a single new station. Typical south Florida incompetence. Still wonder which happens first, Amtrak to MIA, Tri-Rail to downtown, or a Dolphins playoff victory?
Some of the delay can be attributed to Brightline/FECR changing the PTC system as well as changing the dispatching requirements. As far as the delay running test trains, I am not sure if it was negotiations that were tough to agree on by all 3 parties or what was the cause. I would think that since the initial agreement was signed way back in 2017 or maybe 2016, TriRail/Brightline/FECR would have been further along on the test train procedures and had an agreement in place already.Millions of dollars and years overdue for 8 miles of existing track and a single new station.

They had some loading gauge issues which required modification of platforms and TriRail cars around the doors. That probably took a while.Some of the delay can be attributed to Brightline/FECR changing the PTC system as well as changing the dispatching requirements.

Yes. It took some time to resolve that too. I am not sure that was a TriRail issue or an error on the part of the engineering team hired by Brightline to design the platforms. In addition, the approach bridge designs were questioned as far as maximum load stress on the spans at maximum speed. The consulting engineer, who I believe was not involved in the project, raised issues with the design of the bridge spans and the proper loading factor based on AAR design standards for freight railroad bridge designs. He claimed 200% load was the minimum safe design versus what Brightline said was appropriate for a high speed passenger rail service of 120% load factor design.They had some loading gauge issues which required modification of platforms and TriRail cars around the doors.

Obviously there are always unpredictable issues that can occur during any construction project. A sinkhole might open or a find of archeological interest be discovered or the shape of the building cause some weird turbulence or the windows cause some freak light reflection that sets people's cars on fire as happened in London once,Yes.

Of course. But if you don't know which cars will be placed on the viaduct it might be an issue. In this case the viaduct was constructed originally for Brightline trains which are much lighter modern stock, when no one knew that TriRail would want to run its 20th Century style much heavier multi-level trains on it. That caused an outage from the original design, which was easily fixed with additional strengthening. Such is not unheard of and is indeed quite common as older infrastructure is upgraded for use by heavier trains.Obviously there are always unpredictable issues that can occur during any construction project.

But the weight of existing train cars and their loading gauge are known factors that one really shouldn't get wrong.
Wasn't the plan to share the station with TriRail there already when the station was constructed?Of course. But if you don't know which cars will be placed on the viaduct it might be an issue.

As usual it got politicized in the charged atmosphere of Florida and Miami as every politician and half-informed correspondents looking to fulfill their number of articles quotas, sought out possible opportunities for one upmanship. There were a couple of well informed articles, but most were laughable. But that issue got resolved much before the shaving of platform edges and changing out door plates on TriRail cars could be effected to fix the loading gauge problems.
The design of the viaduct had been finalized before Tri Rail came into the picture. Accommodation was kept in the foundation for the TriRail addition, but when the original station construction started it was focused on the three track Brightline station stating that accommodation is made for future extension for TriRail use. Then construction was delayed by a year or two and the TriRail extension was added before the original station construction was completed. Additionally, TriRail was not in a position to enter serious discussions since they had no funding to do so. So Brightline spitballed and added the station without final information about the parameters it must meet knowing that things might need fixing up when TriRail finally engages. Even after TriRail engaged they did not provide all the necessary information. It was only at the 11th hour that TriRail management woke up to the fact that there were issues that need addressing. This caused much finger pointing within TriRail and their management underwent a shakeup as a result, and that is when TriRail got truly serious and started working with Brightline to actually do the necessary fix up, which involved making changes to the viaduct, shaving platform edges and modifying the door plates in TriRail rolling stock.Wasn't the plan to share the station with TriRail there already when the station was constructed?
Or in other words, if the platforms presently earmarked for TriRail were not actually intended for TriRail use, then why were they built as low level platforms?
It seems to me this explanation make things worse, not better.
Fair enough.Even after TriRail engaged they did not provide all the necessary information.

Approximations may be, but the actual numbers are not. The stuff on Wikipedia are not necessarily accurate for the purposes of designing anything, even though us armchair engineers got to town with themFair enough.
I would have thought the dimensions and weights of TriRail rolling stock and dimensions of platforms are in the public domain and would have been available to the planners even without full cooperation by TrIRail management.
But maybe that is expecting too much initiative.
I never heard of remediation being done on the TriRail bridges to the Miami Central Station. Is there a link you can post to this work? I would be interested in seeing what was done. I always assumed that once a bridge was constructed, that it would be difficult to strengthen. These bridges use the Florida I beam construction design. So not sure how they can be strengthened.Of course. But if you don't know which cars will be placed on the viaduct it might be an issue.

I don’t know if any additional physical work was done to get them certified for the higher weight. The whole issue was discussed quite murkily, but whatever was necessary to get them certified for the higher weight was done apparently, since they are now certified apparently.I never heard of remediation being done on the TriRail bridges to the Miami Central Station.

Yeah, the whole bridge loading issue has kind of been brushed aside and ignored. I follow Brightline extensively and never saw any reports of the bridges being certified for higher load ratings. I wonder if this is just the usual Florida way of doing business? I suppose a request for documents under the Sunshine law from FDOT or maybe the FRA (FOIA) might shed some light.I don’t know if any additional physical work was done to get them caertified for the higher weight.

Yes, the single track extension is now complete. I hope to see bookings open sooner than 9/1.

I don't think I'd characterize it as "wraps up". There is still a lot of work going on along the entire route from WPB to MCO. There are many activities related to double tracking all the way. I had previously wondered why they already installed signals for two sets of tracks along 528 when only a single set was being built. Its almost as if there is going to be double track for a good chunk of the route - except for overpasses.
On another note, I got to see for the first time yesterday, Brightline pulling out of MCO. I was parallel to it for a short time as it was going pretty slow. I passed it and wondered if I was going to see it fly by me. By the time I got to Innovation Way, it zipped by. I don't think it was going 120, but 90 would be my guess.
Anyone have a timetable with the speed limits for Cocoa-Orlando?

They had some loading gauge issues which required modification of platforms and TriRail cars around the doors. That probably took a while.
There appears to be some confusion here between "Loading Gauge" and structural capacity. Loading Gauge means defined clearances. There are usually two parts to this: Structural outlines and distances to other facilities, and then such things as platform offsets. For structural capacity the defining values are found in AREMA. (American Railway and Maintenance of Way Association) manuals. The AAR (Association of American Railroads) defines clearances and weights for vehicles, primarily for freight cars. Here is where we find such animals as "Plate C", etc. Generally rapid transit systems each have their own sets of standards both for clearances and for structural capacity. Since TriRail operates on the former SAL and other railroad lines and would be using standard railroad equipment for maintenance, it would seem that they would be following AREMA standards for structural loading. As to this "Consulting Engineer" who was not involved in the project: What is his basis for his claims? Would he even know a good railroad if he fell over it? There are always people like this wandering around making such claims. This is 200% or 120% of what? A year or so ago there was someone running around in California claiming there were defects in the design standards that could cause derailments. No details given. Being as I wrote the alignment standards, including details, it would be interesting to know the basis of his claims. If they are true then I should turn in my PE license, but it seems that all the systems I have worked on are doing nicely, including the Taiwan HSR, could it be that he does not know what he is talking about?Yes. It took some time to resolve that too. I am not sure that was a TriRail issue or an error on the part of the engineering team hired by Brightline to design the platforms. In addition, the approach bridge designs were questioned as far as maximum load stress on the spans at maximum speed.

Nice re: the trip, I'm hoping to take it to an event in Orlando not long after that.I just got my ticket for Brightline trip from Orlando to Miami and back on 2nd September.
Even the first run 5am on Sept 1 is available but I am past the stage where I would drive out at 3:30am to try to catch that train
BTW, the Brightline web site is extremely broken in many ways. In particular, it is a good idea to either print out the ticket or at least jot down the ticket number so as to be able to find the thing on the website later.
Well they lost my entire account. So that is there tooNice re: the trip, I'm hoping to take it to an event in Orlando not long after that.
The website is pretty frustrating (sent them an email about how annoying it used to be to rebook the last-mile transportation if your train schedule changed), but I've never had an issue with a ticket disappearing from my account, ones from September and October 2022 are still there.
