A guest posted they had just ridden on the pink monorail in the front all the way around the MK loop a few days ago (Sunday June 28th). They said the brakes did feel odd when coming into the resorts. They did not feel smooth and always jerked a great deal on and off. Even another guy commented to his friends that it felt like it needed to be serviced. Could be nothing, but as many times as this person has ridden the monorails, it did feel odd, every time they would come into a resort and brake.
Wow, what a shame to think that 15mph could do that much damage.
It's normal for brakes to make noises at times and feel like they are slipping. It's dynamic braking trying to smoothly transition to pneumatic braking. A trick to stop faster is when pneumatic brakes start activating, to feather the MCU up to neutral and then back to B4 braking. Instead of a gradual shift, it will be much stronger.
E-stop simply won't do that. It will go straight to pneumatic at ~80psi. Never ever seen or heard of an e-stop failing. They are tested every time a train is brought out of shop and again during the two daily MAPO checks.
Person on the platform can also force nearby trains in e-stop by activating the kill packs. Even a train in MAPO override will go in e-stop once it hits the dead zone. Trains not using override will stop within 2 holdpoints of the station.
BTW If low air reservoir pressure was an issue, the train automatically e-stops at 90psi. ~135 is ideal for the main reservoir. In addition, the braking system and propulsion system (propulsion controls dynamic braking) are divided into 2 separate computers called group A and group B, alternating axles..
