Hersheypark (HP) Discussion Thread

All B&Ms have proximity sensors that count anti-roll backs and chain dogs as the train enters the station. In this image you see 3 green devices in the center of the image. The 2 outer devices toggle the anti-rollbacks to verify that they retract and come back out. There's a proximity sensor on the other side that counts them. The center device toggles chain dogs and there's a prox sensor on the other side that counts them as well. Only Dive machines have 3 toggling devices as shown here as they are the only B&M coasters that have anti-roll backs side-by-side as shown in the image of a Griffon train undercarriage below. Source All other non-dive coaster B&Ms only have 2 toggling devices, 1 for anti-rollbacks and 1 for chain dogs. Intamins don't have these to my knowledge but a lot of their coasters (as well as B&Ms) have prox sensors that count brake fins. Granted you are correct in that this brake fin counting will not be taking place mid-circuit. -

That would be incorrect. -

I'm thinking it's to assist maintenance in climbing up to the trim brake. They can use it to climb and attach their fall protection harnesses to it. -
^^That happened to us when they let 3 of us ride Green Lantern. We came back into the station spinning like crazy and once we finally stopped, the balance bar that balances out the cars couldn't balance our car so 3 mechanics had to come out and rotate our car manually so we could advanced to the unload area. It was fun staring nearly straight down to the unload platform for 5 minutes.

Here's the best POV so far IMO. This is also the 1st floorless I've seen with magnetic braking. www.youtube.com/watch?v=Cpj_N3AtmDM&feature=related -

They're magnetic trims. There's a pneumatic actuator that can slide one of the reactor plates back and forth to adjust braking force. Image below shows the brake assembly plus pneumatic actuator directly below. The assembly shown in image is part of Intimidator's main brake and not a trim however B&M seems to have implemented this same design for a trim brake on Leviathan. Obviously fully loaded trains will get more braking force than an empty train. This type of trim brake makes no physical contact with the train thus reducing wear and providing a smoother ride for the riders. Source: Carowinds' Intimidator Site -

Those Zamperla restraints are very uncomfortable but looks fun nonetheless. -
