What makes roller coasters pneumantic and hydraulic?

• For hydraulic systems, a sled connects to a roller coaster train, The motor connects uses incompressible hydraulic force. This sled releases to the train, slows down, and heads back, to its starting position. As the hydraulic motor functions, the cable winds around a drum, which pulls the sled. The motor uses incompressible hydraulic fluid in one compartment as it compresses nitrogen gas in another. The power generated throughout this process goes to the cable drum to wind the sled's cable. Hydraulic options when they want faster and smoother acceleration, especially compared to an electromagnetic system. And the launch system as well.
• A pneumatic system functions similarly to a hydraulic one. The primary difference between the two is that pneumatic launch systems replace nitrogen gas and hydraulic fluid with air.
