These coasters make a strange sound.

I always liked it when coaster have that "chuckchuck" sound.

The first link you gave cool5 sounded like the bearings were gone. That sound is more worrying than strange. It may just be the composition of the wheels against the track but I would say is a maintanence issue personaly.

Either way, to me it makes the coaster more exciting lol..

I have been on one of these pipeline coasters, as a lil tot.
