I don't think I have evidence but I have support to back my speculation of it being removed. The whole ride is being neglected it seems. The paint is terribly chipping and fading. Worst I have ever seen. Plus there are many rust spots along the spine of the track. They removed the onride pictures early to mid 2016 season. Brakes are very jerky. When on transport tires, the train tends to skid over the tires. Causing a squeak. The wheels on the train itself squeak (well at least since the last time I have been on it). The wheels on the train also look very used, dirty and old. I personally think the shoulder harnesses were refurbished to look better instead of being replaced. On every B&M I have been on, they all have a flat, gloss paint/coating on any restraint. The paint/coating on Bizarro's seems like a cheap, matte alternative paint/coating. And the Bizarro marquee has been getting pulled apart by park goers revealing the under lying foam. They don't even bother taking some paint to cover up the yellow/orange foam. Or even take a sharpie to it.
In my opinion, the Run Away Mine Train gets better care than Bizarro. And it is a shame too. Its a rather good ride. Seeing Scream get a repaint a couple years ago gave me hopes of a minor refresh. But I fully doubt that now.
