Since this thread got bumped. I really wanted to bump it in June. We were on Yellow (I think) at about 2:00 in the afternoon when they were bringing another train online. So first we were held at MK with the doors open, but then they let the train go, and stopped partway to the Contemporary. The cabin was completely packed, the air conditioning was not working, and this was during the heat wave, and looking at weather for LBV on 6/23, the high temp was 96 degrees.
There is a reason why people are told again and again not to leave children or pets in parked vehicles when it's that hot out. Is a monorail, not moving for 15 min any different? That's a safety issue. When we reached the Contemporary there were a couple Moms that let the monorail crew have it, and you could tell from the body language that the crew couldn't care less, after all what could they do, they aren't engineering, they aren't a manager than has the authority not to load a train.
