Intimidator 305 Track Removed From Kings Dominion

[GavG]

That would be good to have a comparison and see how much difference the changes have made Real.

Coming up first - side by side. I marked them to be identical at the LAST large support on the lift hill. So youll see once Youtube is done, that from there the lift hill has been slowed down a touch (Noted by it reaching a point down the drop first) and it gains speed all the way till the first straight hill. Infact, by that point, original I305 is a train length ahead. After the trims, it loses some ground to New I305 but still finishes 3-4 cars ahead.

Good idea with this video is just pause it anywhere, compare where it is using supports.

What Ill do if I can figure out how to track the two videos is Ill start the comparison at the top of the first camel back since thats where the track is all identical from there on out.



I thought it would track better, but there arent good enough reference points for After Effects to stick too. So, this might be the best we get.

Great video Real!

Very cool video, I'm glad someone was able to do that. Is the original from before the drop trims?

I think so, based on the acceleration it gets

Also consider there may be a decent difference in speed based on temperature and number of riders. The lift speed difference is likely negligable, at least once the ride gets going. They very well may have started using a new material for the wheels, which could affect speeds. If we were to assume all the factors were the same except for the change in track geometry, I'm pretty sure the newer version would be faster after the camelback because A: the current path is a bit more direct between the low turn and camelback, so track length may be a bit shorter, B: lower speed (especially at that point in the ride) means less drag from wind resistance, and C: lower forces means less rolling friction. Only thing I'm not sure of is how the time at the new speeds affects the speed say at the top of the camelback, assuming the new turn takes a bit longer to traverse. Can anyone chime in on that?

very cool, I wanna visit KD again, last time I was there I was 4 or 5 and they still had the sky ride with the singing mushrooms at the Hanna-Barbera land station, anyway, now I have even more reasons to go back. It is funny how I-305 completely dwarfs rebel yell and anaconda.

Something causes the new to be slower. My vote is the wheels. Both videos would more than likely be both early in year. However, ill try to figure that out. But I can count key frames from the top of the first camel and we can compare, but a whole train length ahead by the first of the two in a row, that's fairly considerable. Guess well see by summer.

It's considerable watching it from off the ride, but I can all but guarantee you that the speed difference (if there is any) will be completely unnoticeable on the ride.

I don't necessarily agree boneplaya. I305 may be a special case because so much of it is near the ground, but on rides like Superman at SFA and Storm Runner, though completely different from each other, I've definitely felt clear differences in pacing either over the years, over a few months, or over a few hours. Most of the time it's visible without having to compare videos. I do think it would be less noticeable on I305 given both the layout style and the mid course brake location and type.

That said, it may be better if it paces slightly slower through the middle 1/3 of the ride, because I've heard they have a bit fewer mid course brakes, meaning that trim is probably less noticeable.

And yeah, I think it may be the wheels too since those were much of the problem all along, but the left video does look like it was taken a bit later in the day. Hard to tell because it's not the same camera, and the weather conditions may have been a little different.

My verdict though: no big deal. I don't think it's gotten much better or worse in relation to the first version.

Camera doesnt matter. I key framed it to match, camera isnt going to adjust the time it takes for the train to get from one side to another. I kept framerates the same on both copies. Infact, I searched till I found 2 that were both 720p.

If I wanted too I could have adjusted the one so that it was zoomed in the same distance to match sizes but that is irrelevant. I only wanted to have it so they started at the same point and then you can simply pause it, compare where they are.

When I was referring to the camera, I meant the lighting, hence me speaking of the time of day and the weather conditions.

To many conditions to argue one way or another if its faster. When somebody gives me a years worth of PLC timing data for both versions then we can come to a conclusion which one is faster based on scientific fact. For all we know its running slow because the fresh paint is still tacky.

My friend just returned from Kings Dominion and he liked the new version of I305. He told me they weren't using any trim brakes. At least he didn't notice anybody fainting. That's about all I've heard about the changes they made.

The new leaden on the incline of the first hill seems to be more drawn out, this could actually very gradually slow it down, as friction comes more into play over a longer course.

You people care too much

It is ahead on the original because of the slower speed due to the higher elevation of the curve so that it makes it take slightly longer to reach the end, but it goes basically the same speed after that. Its just a different ratio of speed to track length over the first curve.

Its fast and thats what matters. I doesnt make a difference.

^^ You're trolling a roller coaster forum. I rest my case.

brtn, as I noted the track length is probably shorter because the path is more direct between the flat curve and hill. I don't believe the transition length you noted matters.
