Where do the trains go?
After closing at night, where do they store the trains on the coaster for the night? In the service shed? Transfer Track? Brake Run?

Raptor-transfer tracks safe and sound and "sort of" out of the elements. I am pretty sure this is the rule for most of the coasters

From staying at the campground, I remember seeing the Gemini trains parked on the lift engagement part of the track.

Yeah... they usually park em their and in the station for Gemini. It cracks me up to look out and see them stopped right there.

Iron Dragon doesn't have enough room on it's brake run so they park one in the station, and the other two trains are parked on both lifts.

Disaster Transport just parks them in the station, brake run, and brakes. CP_bound is right about the Iron Dragon -- the transfer track for the Iron Dragon is only used for maintenance or storage (if only two trains will be run for whatever reason).

ON MOST COASTERS THEY PARK ONE IN THE STATION ,BRAKE RUN & TRANSFER TRACK BUT DOOO PUT THEM ON LIFT HILLS

Eh, they do´t put trains on the brake run, and if they do it´s a stupid thing. The brake run needs almost at every time a pressure. If you want to put a train there for the night the pressure has to stay on for the total night. That is an expensive solution, the brakes will brake down faster and they need to be replaced in a shorter period.

I know WildCat leaves them as they are. It is such a pain to transfer trains on and off from doing it by hand.

Rene, that doesn't make much sense though since almost all coaster brakes fail closed with no air applied to them. Secondly, often the compressors are left on at night since very little air is lost from the system. Some brands of compressors are designed only to run when the air pressure drops a sufficient amount from the air pressure setpoint. Brake wear does not occur when the brakes are simply holding a train...wear only occurs when motion is involved. Air is mainly only lost and brake wear only occurs when the brakes are cycling. The only real reason trains are put onto transfer track at night is the transfer track is designed to be an inspection point, allowing maintenance a much easier time of doing nightly/morning maintenance.

Wolfhounde, íf they do it with an vekoma coaster (or a B&M) they don´t make the constuctors happy because the brake system is for short pulsuar brakes and not a contious hold....
I didn´t knew this either but when i was in the efteling last summer I heard it when they transfered the train of the python over there. I think it´s true and the brakes need replacement more often.

Brian, forget everything you know about coaster brakes when you're talking about Arrow coasters. :)
Remember Cedar Point is mostly populated by Arrow coasters. Brakes on Arrow coasters (apart from the ones on Mine Ride, of course, since those are not Arrow brakes) are pressure-applied...the brake caliper is a steel frame with two brake pads inside, a leaf spring holds the pads back against the frame, and an airbag between the frame and the pad inflates to set the brake. Arrow's failsafe involves "powering" the brakes off of a reserve tank and using multiple redundant sets on each block brake. I believe those reserve tanks are generally drained nightly.
I don't know if Cedar Point uses wheel chocks or not on their trains, but I do know that they use chains to secure the trains overnight. A wheel chock would make sense as that would keep the train from moving far enough to fully extend the chains and make them darned near impossible to remove from the train. :)

Yeah, I know those Arrow brakes...makes me shudder each time I think about them. Just not proper practice in my opinion no matter how much they want to argue redundancy.
Rene, as far as the B&M brakes, they do fail closed and are spring applied. Its not a problem at all to leave a train in the brakes all night on one besides the fact there's no real reason to. As for Vekoma, do you mean to tell me that they also have brakes that don't fail closed? Never seen a coaster brake actually designed just to pulse...that usually leads to more wear than less. I'm not disagreeing with you on this...god only knows what Vekoma is doing half the time :).

I don't have a problem with the Arrow design philosophy on brakes. Remember that almost everything you ride in, from semi-trucks to airplanes, have brakes which are pressure applied, with much less redundancy than Arrow puts in the coasters.
Arrow brakes are still default-on brakes, however. They just use air-in-system to force closer.
It does make them more finely adjusted, however.

Well, the nice thing about Arrow's brakes is that because the braking force is proportional to the air pressure, and because the air is compressible, you get a much smoother braking action than on a pressure-release brake. In fact, I noticed that on Son of Beast there are several Arrow-style pressure-applied trim brakes on the ride, although the actual block brakes are pressure-release.
A disadvantage to Arrow's brakes is that each night some other means has to be used for parking the train, because those air tanks have to be drained to keep moisture from building up inside and rusting them out.
Vekoma and Caripro use pretty much the same brake systems as Arrow. I did notice that on Tennessee Tornado the station platform and transfer table are both equipped with pressure release calipers at the down-track end of the platform as well as the usual pressure-applied calipers.

Although Dave,
I have been noticing at night.. them leaving a train at the safety block (after tunnel #3) at night. Sometimes it's there in the morning.. other times.. it's not and there's one on transfer park/ transfer active and station.

Actually Dave, most wooden coaster brakes now are both air to close and fail closed by using two separate air supplies as shown on CCMR. What this allows for is a failsafe (well as far as the air system) brake that can also have its braking force adjusted by varying the pressure. B&M brakes too although closed by mechanical force, also provide braking force proportional to the pressure applied.
Pete, the only problem with your example is cars, trucks, and planes all have from time to time lost their brakes (was in a car once that that happened to). I don't think I'd ever want that to happen on a coaster though.
There are still problems I personally have with Arrow brakes but I don't want to get too deeply into it right now. Bladder brakes are a neat concept but there are better ways to do it now IMO.

I'm a bit late replying here, but I know on a trip a couple years ago we stayed at Breakers and was able to see Maggie early. They had one one train parked halfway up the lift. I think I have a picture of it...
