Erik, could this have been part of why people thought the trims on EGF seemed more forceful last year? It was apparently a colder day than this year. I thought the trims seemed to have very little effect on the speed of the train this year.
Yes, the outside temperature has a very very big influence. While the temperature has also negative influence on the coaster speed while the internal bearing friction on the roadwheels increase at lower temperatures. So the train is slower, and the brakes generate more brake force...
Interesting. I rode GeForce in 2007, not with TPR, but on my own visit. The general TPR consensus was that GeForce was not up to its usual standards in 2007. I went to Holiday Park on Aug 1, 2007 (which I believe was shortly before or after the TPR visit) - the day I visited was warm and sunny (once again, I was wishing for sunglasses on the loading platform and lifthill). On Aug 1, 2007 GeForce was running GREAT - it instantly became my number one favorite. Personally, I didn't see too much difference between the way GeForce was running on my 2007 visit and the way it ran for us this year.
