a real life gearbox has an efficiency of 98-98 percent while storm works ones have 95 percent!!!!!!!! my train which uses a custom engine and has five gearboxes and has an efficiency loss of 23 percent I feel like if the gearboxes weren't so heavily debuffed it would be kinda nice or no efficiency lose when the gearbox is 1x1 and then increasing efficiency lose the higher you go like 1x2 98 and 1x3 being 97 which seems more realistic and doesn't steal so much power. along with that, maybe larger gearboxes could be more efficient I can imagine that a 1x1 gearbox could be less efficient and a 5x5 being super efficient with low losses. since they seem to serve no purpose currently
