I have ridden all 4 Mark V's and know that Mark V Orange was badly damaged and is being reversed engineered at WDI's HQ. IDK anything about Blue ever rolling off a switch though, either that or the damage wasn't bad but it got converted into Mark VII Red.
I'll have to find the details, but somewhere (Monorails.org or MiceChat) we dredged up the story - Monorail Blue was supposed to go onto the mainline after some brake system repairs and they pulled out of the barn, but the switch wasn't lined right, so the pilot stopped short.
Problem being, the DL Monorails don't have spring brakes AKA air-brake parking brakes, and there was still an air leak. And the train lost air pressure, the service brakes released, and the train s-l-o-w-l-y rolled forward and off the end of the open end of the beam before the driver noticed or could react. Main power was not on so the air compressor was off, and the driver couldn't power back up and throw it in reverse in time.
And AFAICT they still don't have spring brakes on the DL trains, a very simple safety measure - you lose service air, and the spring applies the brakes. Been using them on heavy trucks for 75-plus years. The Tramzillas have them, you hear the air release when they stop, and the recharge before they pull out.
"But you can't tow a disabled Monorail train back to the barn with the brakes applied!" S'okay, they already hook up an air hose from the Monorail Tractor's compressor to provide air for the trains' service brakes, so it doesn't shove the tractor a quarter-mile getting stopped... It's no big deal to plumb that same air supply to disengage the parking brakes too.
