Every time I see the be of these I think, it looks terrible, but it's not an inherently awful product that couldn't be improved with a slight change. All they need to do is ditch the idea of the quasi-dueling passenger trains and it's already a less clunky idea.
Having one single small train zipping along the track doesn't look as impressive as the crossover/high five aspect of these rides, but it'd cut the noise by a large margin, and only having one small, lighter train to push on those drive tyres might result in a speedier, more thrilling ride. I know the manufacturer will never do it, but I wish they would because I just can't picture this concept sticking around for years to come.
