I love this testing video. This looks like one of my RCT coasters come true (read: perfect ops and tight dispatch intervals hit again and again).Testing with two trains now. Looking fantastic!
Really hope they do commit to the four train operations, or even three at least.
I guess they will end up running 3 trains using a 4th to rotate or for spare parts. 4 trains would require guests and crew to be extremely efficient at all times, which is virtually impossible. There is always slow guests, people who decide not to ride last minute, etc.
