Wind, weather, and coaster physics
Headwinds steal speed; cold affects grease — operations limits are physics-based.
Headwinds increase effective air drag — trains may not reach usual speeds into exposed hills. Tailwinds are rare bonuses but not guaranteed.
Cold thickens grease and affects wheel compliance; parks may delay opening coasters until components warm.
Empty trains in high wind have less momentum — some parks raise wind speed limits when trains are light.
These are safety policies derived from how forces scale — not arbitrary mood from operators.
