Right. I worked in Monorails for several years and was a part of multiple live evacuations and drills myself.
I agree that a train being stopped because of a lightning strike is common. I remember piloting a 2 hour 43 minute lap on the Epcot beam in Monorail Black because all the MAPO transmitters were fried, meaning I had to be cleared point to point around the entire beam. Luckily I was deadheaded, so no guests were impacted.
However, evacuating guests via the ladder and having them climb on the roof of the train (if reports are to be believed) is fairly rare. I believe the last full evacuation was the power outage in December 2009, which I was involved in.
I'm not saying Disney is at fault in any way. But I believe that this is fairly interesting news, which is why I posted it into the news forum.
