Not sure if this was posted somewhere else but I stumbled across this footage of one of the Top Gun models testing
Judging by how well it maintains speed around the track, it looks like Vekoma have finally ditched tapered roller bearings in the wheels and gone for good ole ball bearings.
Aww yea, that's a nice train?
I'm seeing hints of Intamin in that chassis and wheel assembly design and I'm liking it. Now if only I could persuade someone to upgrade to these new trains......
