Like previously stated in a topic regarding Deja Vu, why do they not just make the ride with LIM's?

I know someone already stated that Vekoma already tried that before, but why doesn't Six Flags seek outside help in finding a way to fix the ride?

And even if LIM's are not possible, they could try something else. Does anyone have the true reason LIM's were not used in the original design or the post design to fix the problems with them valleying?

Has Vekoma ever used LIMs on an invert before?

Are the trains built in such a way that they can attach to the cable lift AND use LIMs for propulsion, without the attachments for either getting in the way of the other (And if that sentence made sense, you're a smarter being than I)

Like I said, they could seek outside help, IE Intramin AG who has used LIM's on inverts. And if these LIM's were to be set in place, they would be on the adjacent tower (second) without the use of the cable lift.

Anything is possible if enough time and research is put into an idea. I really don't think Six Flags wants 3 green and blue ornaments sitting in there property just for people to look at.

Anyways, it was just a thought. Any more comments or ideas?

Has Vekoma ever used LIMs? I know they use LSMs on the Rock 'N Rollercoaster models, but I can't remember any LIMs. Another thing to consider is that standard LIMs seem to require straight track, which can't be found on the ride aside from on the lifts or in the station.

What about the station? And they could use the LIM's as brakes too.

Vekoma originally tried to use LSMs instead of a chain on the first Invertigo. I'm not sure if they were trying to do a California Screaming type thing with a normal speed lift powered by LIM/LSMs, or an actual 0-56mph launch, but either way, they've played around with inverted coasters and LIM/LSMs. How practical and economically feasible such developments would be on the Deja Vus? I guess that's for Vekoma and Six Flags to decide.

LIMs are cool and all, but I think people jump to use them too fast (at least on this site I mean.) They're actually very power hungry people, and the savings and benefits of a LIM system, especially on a Deja Vu which would require enormous power to pull that train up vertically, would probably cost the park more in power than it would to mothball the ride and have a "green and blue ornament"

I'm not convinced that LIM launches take more energy than conventional chain motors. They take it all at the same time, but the end result is the same amout of potential/kinetic energy in the train. LIM's probably have more overhead from resistance in the circuits, but I wouldn't guess it would prohibitively more.

The real issue is a) Vekoma hasn't done much LIM technology

b) you can't just slap LIM's on an existing ride. Trains would need redesigning, all the control circuitry would need redesigning, the track structure would probably need redesigning, etc. etc. etc.

I don't think any coasters use LIM's as brakes. The impulses and other Intamins use totally independant magnetic braking systems, and the premiers use conventional fin brakes.

Sure, Six Flags would like the ride to run, but it's not as easy as "Oh let's just slap some LIM's on it and it'll work fine." I mean, in addition to the magnitude of that kind of reworking, what guarantees them that the LIM system will work any better (which really means at all) than the current cable system?

LIM launches DEFINITELY take up more energy than a chain motor. Some LIM rides need their own power lines so as to not grey out their surrounding town. I do agree with Andy's whole argument though: the whole thing is just a little too messy.

I play in a really awful garage band, but it's still fun.
