I do not post as I do not have much to add to the conversation. But to those that do thank you this forum is a great read. My top hat is off to all of you.
Project 2022: Pantheon

Here is a video that I found of the "Soaring with Dragon" coaster in China. This has the shuttle triple launch section (without the small hill in the launch section). Also, the layout is very different from Pantheon at BGW. The train dispatches out of the station directly onto the shuttle launch section. Once the train is on the launch track the switch track moves and then the forward-backward-forward launch sequence commences. At least it gives you a feel for what will occur on Pantheon.

Ok...back to the coaster -
We now return you to "Larry Giles Said"; already in progress.
- Spike is 178ft. Terrain in that area is about 70ft. So I assume an FAA light? (It would be cool to top it with a trident). It's also about 10ft taller than the Asterix stats, so I assume that why the backwards launch is a bit faster.
- Switch track. Hagrid has it. I know that ride has issues but has anyone heard anything specifically about switch issues?
- Drop is 180ft. With terrain factored, the top hat is about 150? (Asterix stats was 147ft.).
- Top speed is stated to be 72.5mph. Astrix was 66.5mph. I can't recall if BGW said whether there's a stall at the top (PA does). Given the final launch for both is 67mph would no stall give that extra 5mph?

I asked a universal local who tells me hagrid has has 2 e-stops after the switch to valley in the dip. One was an evacuation, and the other they launched out of it to continue the course.
Call me crazy, but for new technology...two out of the many dispatches Hagrid has had isn’t HORRIBLE.
Remember, the ride's PLC only does what the programmer tells it to do. Being safe, they programmed it to e-stop if there is ANY discrepancy on that switch. Since there are most likely a few dozen different sensors on that piece of track alone, there are a lot of potential discrepancies. Better to be safe and shutdown a few times than crash.
My point exactly, I think Pantheon will be fine. I’m excited for this ride!
Every new ride system will have it's issues. I happened to be working in the area with Log Flume the year it got a new control system and you would not believe how many 10-11's we had to do because the PLC E-Stopped itself and the ride drained (what happens when an E-stop is hit on a water ride).
The forces on the hilltops will vary as the speed at each varies. There should be 5-6 points of airtime on the hills...I'd imagine the first dip wouldn't get below 0G despite what the Park Asterix video says (it has the same force for all 3 runs at that dip which can't be true), but the rest I'd expect to be within that range and what FoozMuz posted.
Not to dispute @DC High Heat ...I was transcribing the figures as he posted. He knows more about this stuff than I ever will. ?
Just adding to what @FoozMuz said... Here's the entire launch sequence pulled off the Intamin presentation -
[Switch track] -0.5g, 0g, 0g (top hat stall), -1g, -0.5g, 0g (backwards spike stall), -0.5g, -1.2g

1. No FAA light as the requirement is 200 feet above ground level but sea level. If it were sea level then Griffon, Apollo and Alpen would all need FAA lights.
2. I have not heard of any issues with the track switch at Hagrid's. So while the ride itself is having issues it seems that isn't the culprit.
3. That sounds about right.
4. Based on the PA video the ground under the top hat is level unlike at BGW. So I think the drop from the top hat is likely 30-40 shorter than BGW. This probably accounts for most of the speed difference. From the teaser video of Pantheon it looks like the coaster isn't going very fast over the top hat but it doesn't look like it has a break like PA. So that probably accounts for an extra mph or two and the rest is based on the drop height differential.
I imagine that with the fast track switches on Pantheon and the PA coaster that the first launch/dispatch won't go until the switch track is in place, which won't change over until the train clears the top hat. Now how quickly does the train start accelerating while it entering the middle launch section? Enough to get it going, but still slow enough to stop the train before it returns to the switch? I imagine this is the case.
There are only two trains so it's likely that they will be loading the entire time that other train is on the course they are loading and they went dispatch until the next train arrives at the final brake run.
As far as the speed we know the speeds of all 4 launches. The first launch is 36 mph. That is before the switch track. Then once inside the switch track they are 50, 61 and 67. They will be gradually increasing the speed of the train over the course is the launch track. All of the launch track also doubles as brakes. I would imagine that if the track hasn't switched before the train reenters the launch area from going partially up the hat that it would stop the train.

From the asterix video it looks like the first of the triple launch does not start right away, it is likely looking for switch confirmation before adding any energy to the train.
