PortAventura: General Discussion

I’m not one to guess but. - steel prices are through the roof. Maybe less quality steel has been purchased leading to less quality rise?
 
This is probably a stupid comment as I know nothing about the engineering side. But in relation to this and the Nemesis re-track; could it be anything to do with the the old style trains on the new style track, could they be a few extra mm out which is causing the vibration on the wheels?

That wouldn't explain why so many brand new B&Ms are also opening with marked rattles, though. Many B&Ms from the early 2020s onwards have had heavily criticised rattles.
 
Didn't it recently come out that their margin for error on every piece of track has ever so slightly been increased to make the cost more affordable for the end purchaser?

We are talking microscopic differences here but of course but that will still have an impact on smoothness.

Maybe this was needed in order to remain competitive in a very tough market but from a B&M fanboy perspective, I would have preferred they remained the silky smooth rides they once were.
