Also, at the physical switch (in the Shop), is there any visual indication that the switch actually moved? Any security cameras on the actual switch so that the move can be visually verified?
If I remember correctly, there are cameras pointed to each of the switches and these are monitored back in Monorail Shop. There used to be someone who was dispatched to the switches to visually confirm proper movement, but the cameras replaced that.
Has Central ever directed someone to switch rails, and at the last moment changed their mind without announcing it? Could the driver have assumed Central simply changed their mind where they wanted the train based on previous experience?
Based on when I worked there, no. It takes some effort to position the trains for a switch and then to call for the switch to be moved. Even if there was a last-minute change, the pilots would be instructed accordingly.
But being in override would have enabled him to move the monorail if he saw Pink coming towards him, correct? Taking his hand off the button would have cancelled the override and put him in (I'm guessing) an e-stop meaning he couldn't move the monorail. It's just a guess on my part :shrug:
Even if a pilot is getting a red MBS for the track ahead, it has no bearing on the train's ability to reverse. The trains see in the direction in which they are being piloted, so, as long as the track behind Monorail Purple was clear, the MBS would have turned green as soon as the train was switched to reverse. The only problem is that this does take a few seconds and it could still have been a few seconds too many to make much of a difference.
It seems like I read somewhere a long time ago that if an e-stop occurs because a pilot wasn't paying attention that it's a really big deal in part because there has to be a reset of some sort to disengage it. I don't know if that's accurate or exactly what it means but my mind's eye conjurs images of a time lapse akin to rebooting your computer.
No, this is incorrect. A MAPO (red MBS) clears as soon as the condition causing it to appear is resolved. For example, in normal opearation, it would clear as soon as the train in front (to which the train receiving the red MBS was too close) continued far enough forward. First, the MBS would turn amber, then, as the train ahead moved on, the MBS would turn green. Likewise, if a train has a MAPO while moving forward, throwing the train in reverse would quickly change the MBS to green if the track behind the train is clear for the required distance. The only issue here is that it takes a few moments for the brakes to be released after an e-stop of any kind.
Now, with the possibility of reversing in question, there is something very important to keep in mind. In fact, it is something that most Monorail pilots (myself included back in 2006) learn very quickly after they start driving. In order for a train to be placed in reverse, it is absolutely essential that it be stopped first, then put in reverse. If this is not done, the train will realize that it is being told to go in reverse, but it knows it is still moving forward. This will result in a train control failure and an automatic e-stop and will require use of the train control override (one of the switches located on the panel behind the pilot) to get the train moving at (I think) 20 mph into the next station, where the train would be reset. Just as it was my first instict to immediately flip the switch to reverse when I overshot Base (TTC on the Express side) by quite a few cars, it may have been the pilot's first instict to flip the switch as soon as he saw Pink rolling towards him. At that point, it would most likely have been too late to grab for the override switch and get Purple to move.
Although I am no longer a WDW Cast Member and did not know this particular Cast Member, this incident really fills me with sadness. From everything that I have read, he seemed like a really great guy and my friends in Monorails who did know him have been saying the same thing. I feel for his friends and family and for all of the Monorail Cast Members. I am proud to count many of those Cast Members as my friends and I know that they will pull through this stronger than ever. One Rail, One Family!
