Looking at the trains there seems to be big gap between each car, could the fins on the lift be used to rotate the seats to face backwards?.
(Sits back and waits for all the abuse for making a stupid comment)
Can we please keep this topic to what is known about the trains, this should really be in the Speculation topic here
Now back on topic
Who is to say they can't test while there are workers on site? A logical answer would be as long as none of the workers are in any of the ride areas (like in the fenced off section near the lower section or in the pit for example) then they can test. If they are in what will be public areas like the queue line, the shop, the top of the steps, ect then there is no problem.
There were workmen on and all around the track and site yesterday, including in the station, which would seriously infringe health and safety regulations. I would think we should see some daytime testing next week sometime looking at what was going on on site anyway
