Hey ForgottenEE, if that's the case, why don't they consider coating the wheels (or at least the outer circumference) in Teflon or a similar substance. Along with that, perhaps ceramic bearing could be used (although they probably are already). Wouldn't the combination of the two greatly reduce rolling friction?
On a side note, I'm glad my Photoshop work could be of assistance to you all in the debate at hand.
Thanks for clearing that one up Vince. :)
As for the wheels, harder comounds, better berrings, thinner grease would all help with slow speed operation. The problem is they affect the high speed operation too. MF with the current setup is very close to over speeds on hot summer days. The less friction the wheels produce, the lower the maximum temperature the ride can run in. Right now it's a good median from cold and warm weather operation when loaded. When the weather gets cold, the ride requires a certain amount of weight to operate. Water dummies in the morning, and later fully loaded with guests. It the ride runs consistantly, the wheels stay very warm so there isn't a danger of rolling back. The first runs of the day, the wheels are nearly as cold as the low temperatrue that night.
The effect is the ride is much more sensitive to the weight in the train. There isn't a huge difference when it's warm out like there is when it's cold from empty to fully loaded first run operation. It's perfered to used weight untill it becomes impractical then they start to heat the wheels. The colder it is, the more weight then heat is used. Once running the ride runs pretty good in cold weather. Wind might be able to shut the ride down in any case. If it's cold and windy, the ride might not be able to run. It's rare that it can't open due to weather, and MF runs when most the other rides in the park cannot.
MF has rolled back twice to my knowledge. Once in 2000 when it was cold and there was no weight or heat. The seconds time it rolled back was in 2002 with some dummies. Apparently the manager wanted the ride to open on time so he didn't put enough weight on the train...
Overall, the current setup is a good balace between low and high temperature operation.
Not to be a stickler (ehhh, who am I kidding?), but the "at" in "Where at in..." is absolutely unnecessary. It's a preposition that can easily be omitted, and the sentence can be read in the same fashion (with the same meaning).
So, seeing as I also had the same question, where in the track's layout did they roll-back?

Those locations are correct. The red train rolled back between the overbanked turn and the 182' hill in 2000 empty. The blue train rolled back and stopped somewhere out on the island. I happened to be there that day for the winching of the train over the stretch and last overbanked turn.
Colors on a palette can't really give you the best idea of how it will look when finished. That sample color also doesn't give the glossly shine it has when the sun hits a 3D surface.
