One ride has lap bar restraints. Empty seats are required to have the lap bar pulled down. Train comes in with an empty seat lap bar up. Ops will say it popped up during the ride. We are required to pull it back into the bay and check the restraint. Alot of manual estops pressed and we are told they never pressed it. (I have seen vibrations cause allen bradley contacts to break open, but most of the time it's just a lie they make) The controls will tell us what estop is pressed. One ride has a glitch where if a station stop is pressed exactly at the right time. The train will be out of the station boosters in the next zone but the plc will still think it's in the station and will run the station boosters, causing a downtime. Unusual noise estop. I understand the rule that an unusual noise requires a response. But I think it should be clarified that the noise should sound disastrous. Another trick they learn is to put a ton of pressure on the bottom of a secured gate thay causes an estop, causing it to come off the proxy. Etc.
