qldtaw 6 Posted August 21, 2017 Report Share Posted August 21, 2017 Maybe i missed something in past posts... but did they ever do a pull through of the car? I would have assumed we would have seen footage and pictures of this before test cycles... And i thought a pull through was standard to make sure the track was complete and the train can cycle without obstruction. Have they created new devices/technology/processes to avoid the need for this? Link to post Share on other sites
pin142 799 Posted August 21, 2017 Report Share Posted August 21, 2017 Guessing all the work done around the track in the weeks prior was sufficient enough to allow them to go full speed testing without needing to pull through. Link to post Share on other sites
diesal11 32 Posted August 21, 2017 Report Share Posted August 21, 2017 Well if the track & supports are made & installed to spec it would be fine in theory. You would notice pretty quickly during construction if something didn't line up. Although we had that exact scenario with the Stengel Dive support? I thought the pull through was to check clearances anyway? Link to post Share on other sites
red dragin 381 Posted August 21, 2017 Report Share Posted August 21, 2017 With the way the track pieces interlock, and wide open clearance around the track it doesn't look necessary to do a pull through. Link to post Share on other sites
Tim Dasco 794 Posted August 21, 2017 Report Share Posted August 21, 2017 Have a look around the helix area and the NIL. I would say there will be a lot of near misses there. 2 Link to post Share on other sites
MickeyD 938 Posted August 21, 2017 Report Share Posted August 21, 2017 They wouldn't spend tens of millions on a new ride to accidently wreck it on a 1st test! Gotta say I was surprised too but the very fact that actual people rode it later that same day suggests overwhelming confidence in the safety and performance of the ride's design and construction.

AllegroCrab 214 Posted August 21, 2017 Report Share Posted August 21, 2017 They could just be smart and not put their hands up at that part until they've done pull throughs. 1 Link to post Share on other sites

Popular Post xRazzBerryx 271 Posted August 21, 2017 Popular Post Report Share Posted August 21, 2017 PCL posted a video from a test run this afternoon & I must say it looks a lot faster in this video, especially coming over that airtime hill! Not sure why it looks faster, maybe it is the angle the video was taken from but it definitely looks faster to me. 6 Link to post Share on other sites

Not sure why it looks faster, maybe it is the angle the video was taken from but it definitely looks faster to me. Could be to do with the chain lift - the videos on Saturday appeared to show the train slowing for the crest of the hill whereas now the chain seems to retain its full speed as the train tops the hill. First videos of Flash had a slowed chain lift too, seems to be the practice for first day testing. 4 Link to post Share on other sites
red dragin 381 Posted August 21, 2017 Report Share Posted August 21, 2017 I think the chain speed too. By adjusting the initial speed (chain) you can also tune the speed of the coaster. Link to post Share on other sites
jack.c 125 Posted August 21, 2017 Report Share Posted August 21, 2017 Random question, would the forces be different whilst sitting backwards compared to forwards? Link to post Share on other sites

The magnitude of forces will be exactly the same, just the direction may change. The vertical positive/negative would be exactly the same as if you were sitting forwards. The lateral forces will switch sides because your left becomes the train's right, and the forwards/backwards forces will switch direction because your forwards is the train's backwards. 1 Link to post Share on other sites
xRazzBerryx 271 Posted August 21, 2017 Report Share Posted August 21, 2017 I compared both the videos from testing & the one posted today seems to complete the course roughly 6-7 seconds faster than the first day of testing. Link to post Share on other sites

Not quite. G-forces are a product of speed and directional change, i.e. the track curving. All rows of seats are travelling the same speed at any given moment, but they will be on different sections of track and as such experience different forces. The easiest example to think of is heading over the top of a lift hill. While the front rows will creep gently into first drop experiencing essentially no forces, the back row is often whipped over with a burst of negative g's. 4 Link to post Share on other sites
AllegroCrab 214 Posted August 22, 2017 Report Share Posted August 22, 2017 Yeah, that's a more complete analysis for the entire train. I was lazy and just compared what would happen if you switched the direction you were facing in the same row. Another interesting thing to think about is how there is a difference between sitting on the left or right seats. This is especially noticeable in coasters with 4 (or more) abreast seating, where the seats at the extremities have to move a longer distance than the seats in the middle for the same twist. If you compare the leftmost seat to the rightmost seat on the same coaster, you'll get different forces for different elements depending on their shaping and which way the track is twisting. So when trying to work out what the best seat is on a coaster, not only should you compare which row you are in, but also which seat you are in on that row. As always, it comes down to opinion. Some people love being whipped through elements, some people love it to be graceful. Always gives you something to argue about for ages with strangers on the internet. 1 Link to post Share on other sites
