Can someone advise about the correct wheel replacement for an Athearn U30B diesel that is 15-20 years old? From searches here this is what I came up with.
37142-4 HO 42in/110 half axle, inside frame wheelset
I sent a request to NWSL 3 days ago but have not yet gotten a reply.
According to some specs I found, the U30Bs actually had 40" wheels, so these would be more appropriate. All Athearn BB diesels use the same wheels and axles, so the NWSL wheels will fit all models with the inside frame truck design (they also make wheels for the older outside frame Athearns).
