I've always been curious and hope someone has an answer or at least a good guess for me... I've noticed mainly on inverted impulse coasters such as Wicked Twister and Possessed, there are, what appear to be, blower motors alongside the LIMS. Like these circular devices feeding into the side of the LIMs. Closest thing they resemble to me is either water or air turbines. I've always been curious about what they do. I've noticed a sound that seems to be air rushing throughout the station, even when the train is stationary. Are these motors just cooling for the LIMs? A small thing but I've always wanted to know how coasters work and this has been a big thing that has stumped and bugged me for a while. I can't find a picture of them anywhere. Anyone know what I'm talking about? I feel like I'm nuts lol...
