While down there yesterday afternoon I seen it go up the lift hill very slowly then stop for a minute or so then carry on, surely they wouldn't do VR testing over a bank holiday weekend?
Possibly. I'm not sure how testing with VR works. If there were passengers with headsets on testing, then it could be testing to make sure the VR aligns with the track and movements on each carriage.
I think it could definitely be VR testing, whether it be testing when in a E-Stop situation or maybe pin pointing the VR sequence. Also could just be general matinencr whilst the ride is shut.
