I LOVE looking at the Hydraulic rooms of Intamin Accelerator coasters. When I worked XC @ KBF, I had a good relationship with maintenance so they would always let me look around and would explain each component and its function. When you see this equipment in action you have an understanding and appreciation for the work that it takes to keep it running. VERY complex system. Being in the room when a train launches is definitely an eye-opening experience. The sound the winch makes while launching is music to my ears.
Yes I know, I'm an Intamin fan boy.
