There are actually quite a few facts known and most of the discussion here is relative to that. The fact is that there was a crash at a station that stopped the movement on that line. Gondolas in the stations were evacuated quickly. The fire department arrived to evacuate gondolas on the line and evacuated a number of them (not a fact but maybe 6) using aerial ladders and other equipment. The rest of the gondolas sat on the line for 3.5 hours until they were moved back to the station. The majority of the discussion has been about the 3.5 hours.I was going to write the same thing. 90% of this thread is speculation at this point.
Might be a while until we know the exact facts
