Vekoma Coasters - CoasterBuzz

It's me again, with another question about roller coasters. I was wondering why Vekoma roller coasters always have like and extra wheel behind the trains. Like on their Suspended Looping Coasters, it looks like they have room for another car, but I know it is just there. Also, on their Boomerangs, there is an extra set of wheels trailing behind the train. What's up with that? Tell me so I can be enlightened.

On Boomerang's it's to pull the train back up. It lets go once you get to the top.

I've been wondering that myself! It looks really odd...I think a few Arrow coasters have them too! Someone told me why they had them on the Serial Thriller at SFAW, but I know it was not true. He said that there was once an extra car there, until someone hit their legs, so they removed it. I seriously doubt it!

If you'd place the wheel assembly right above the heads of the people, with nothing else supporting from the track, there would be way too much wear and tair on that one pair of wheels. SLC's would become even more bumpier, imagine that. It's called an articulated train, on which the chairs hang on the crostie bewteen two wheel-assemblies. For example, beemers have them in the front of the train: the dummy car.

On boomerangs it's simple, just like Arrow trains. The cars are trailered. I think the front car has it's own single axel in the front, but it's back wheels are shared with the car behind it, which use them for front wheels. It goes like that to the back of the train, where the wheel assembly is still the same type, but there isn't another car to use them as front wheels, to they just sit behind it doing nothing but following the train, and supporting the back of the car in front of it. Someone else could explain it better, but I tried...
