Sorry, I thought you were talking about the track pieces, so I limited my link to just those. Unpainted Unitram road/block pieces are also available from Japan, if you need more than you already have.

reached out to another N Scale traction modeler and got the needed advice....

That's a good news John!
So, the inquiry minds would like to know what the solution was.  It could even help someone else here looking for this solution in the future.

Magic Eraser is just very fine sandpaper.

Make sure you are using 91% or higher IPA, I've had ZERO luck trying to strip Kato cars & locos with 70%, but almost 100% using the stronger version.

Unless there are earlier versions, I think these are all UV printed.  Which means alcohol isn't going to budge the printing. 

Strong tape may lift off the markings, otherwise you're going to have to sand them off.
