I have a couple of Berkshires and a Hudson, they seem to slosh side to side. Any fix for this?
My guess would be the wheels are out of gauge - probably a bit narrow to allow them to more easily go around the tight (14-15" radius) curves common on European layouts. Depending on how the drive wheels are attached to the axles, you may be able to slide them out a little bit. Having an NMRA track gauge would be helpful!
I’m not sure they’re running Nickel Plate Berks on the continent, but maybe.
Another reason for a wobble might be a deteriorating traction tire.

I don’t have any experience with non articulated Rivarossi locomotives but the Rivarossi running gear or side rods make them wobble. I went to a dual motor configuration and that all but stopped all the wobble.
Check the slack in the side rods, excessive slop will cause wobble.

I’m beginning to realize that aging is not for wimps.
Rivarossi was an Italian manufacturer before being bought by Hornby or whoever owns them now. For many decades they made models of European and US prototypes, but made to operate on European layouts (European style couplers, and for a long time, very deep wheel flanges.) Layout space is much more limited on the continent and the U.K. so a lot of European HO or British OO equipment is designed to take curves down to around 14" radius.
Yeah, I had a challenger (which I should’ve kept); I don’t remember it sloshing around like the others
