Pete is correct about the anti-rollback disengagement system requiring the high speed to function. Wednesday morning, the red train was parked on the lift and when it started, it was noisier than Magnum until it got up to speed.
While waiting for the trains to be swapped yesterday I had an opportunity to chat with one of the crew members at length, and he noted that indeed, the big problem is that the unload approach brake has to be completely clear before the train on the lift can be allowed to crest. Originally, I guess the unload station had to be completely clear before the train on the back brake could move, but the change is to allow both of those trains to move together. That seems to work, as I saw it in action when they transferred trains. I think the motion starts as soon as the loading station is empty; I wouldn't be surprised if they try to push it even earlier...after all, there is a kicker wheel at the uptrack end of the loading station, and once the train starts to dispatch, there is no way for a following train to catch the lift pusher...as long as the train departing is faster than the train entering, they could move *all three* trains together.
There are three issues at work in the unload station that need to be addressed. The least problematic is that people are getting stuck in the train because the seat belt buckle is unfamiliar. Heck, they could probably fix that with a sign over the approach brake with a picture of the buckle and a sign saying "UNFASTEN SEAT BELT NOW".
The second problem is that people keep trying to exit the train to the left, since there is a platform there. I wonder if a piece of strap could be run from the outboard siderail of the left-hand seat to the grab-bar, much like the steel plates that used to be on the side of the Blue Streak.
Finally, I noticed that they were waiting for all exiting riders to start down the stairs or ramp before they sent the train into the loading station. While this is a good idea from a safety standpoint, it's bad for throughput. Perhaps they could simply wait until everyone is clear of the Yellow Line...install a light curtain or a touch mat if they're really worried about it...to speed up that process.
