DiogoJ42 said:Not every coaster uses them. Woodies, for example, or Arrow coasters such as Vampire, simply have the station and brake run on a slope. Of course, this means that Vampire often gets stuck on the brake run if the train is lightly loaded, and needs a push to get it going again (a flaw that never happened with the old heavier trains).
DiogoJ42 said:You can see the slope of Vampire's station track quite clearly from the ramp as you enter the station. The lack of kickers is why it has to stop about three times before the train parks correctly. The aging computer says
"OK, let the train in... YIKES! It's too fast! quick, apply the brakes! ... OK, release them and let it roll forwards again..."
This cycle repeats several times :
To attempt to stay on topic...
Someone mentioned a while back the idea of using kicker wheels to maintain a constant speed through a barrel roll. To me that seems like a bad idea, as if there was a power failure or E stop the train could get stopped upside down.
While I know this has been done before...
I somehow doubt it would be allowed in this day and age.
I think that depends on how the motor > wheel drive train is geared.BigAl said:If the barrel-rolls were going downwards and the shuttles/trains were merely controlled with friction/kicker wheels then if the ride did E-stop, would it not be possible to have some kind of manual release to allow the train/shuttle to roll to the end and come to a stop the right way up?

If you're after a constant speed for a theatrical effect that's much slower? Probably pointless though as it probably wouldn't be fun!John said:Why would you need kicker wheels anyway? If you build the track at a very slight gradient the trains will be travelling at a roughly constant speed - just look at the 4 rolls on Colossus.
