I don't know why Dorney insists on using them instead of air gates.
My question is, does anyone know of ANY other park that uses magnetic gates in a coaster station? I've just always thought it was very odd thad Dorney has them and wondered if they actually exist anywhere else.
At least you don't have to worry about people breaking the air gates and then shutting the ride down.
They sometimes make an announcement and say "Push on your gates" which usually helps as well.
Hobbes: "What's the point of attaching a number to everything you do?"
Calvin: "If your numbers go up, it means you're having more fun."
Magnetic locks are not as prone to this problem, however, you can still kick your way through some gates that are magnetically locked (Please don't try and find out which ones!).
If you were to push the air gate very hard when it is closed, you can actually cause the ride to shutdown
That happens pretty often on the Mack built Avalanche at BPB, UK. There doesn't seem to be too much force behind the gates and sitting on them does cause them to open and you either see the train stop or get yelled at by an operator.
Nothing to see here. Move along.
Roar was the first coaster in the park to use air gates back in 98,but even then everything else in the park had that simply cable system to keep on coming riders out of harms way.

If you had one, I'd think you'd also be able to create faster dispatches--that's if the magnetic gates are such a hassle and if the air gates being manipulated in a method that caused the ride to be shut down. Not only that, but it would free up time for the mechanics if they have to respond to the ride being broken down from the "proximity sensors"; they would be able to spend their time in other areas.
It's entirely possible that I'm wrong, but I'd think that it would actually save money in the long run.
Edit -- The above ideas are mostly practical to new installs. I'm not suggesting that parks completely overhaul the current gate systems. *** Edited 10/22/2006 11:56:28 PM UTC by Infamy***
Put a lightweight spring on the gate so that when the magnet is released, the gate pops open by itself. Then the attendant just has to slam all the gates closed once the magnets are re-locked.

(who thinks boarding gates are a waste of time and effort, but exit gates are not such a bad idea...)
Using airgates and magnet locks are unnessesary. They could easily operate the gates at a low pressure and hold them at full pressure when closed to lock them. Easily done.
Care must be taken in any case to prevent guests from being squished at high pressure.
I thought there was a standard for "Boarding gates, when used..." but so far all I can find is "Ride or Device Vehicle Doors" which provides the following advice:
ASTM F 2291-06a:126.96.36.199: Powered doors shall be designed to minimize pinch points and entrapment areas. The doors' (opening and closing) movement shall be controlled, and the maximum exerted force, measured on the edge of the door at the furthermost point from the hinge or pivot, shall not exceed 30 lb (133 N).
I thought sure there was a similar clause for platform gates...
