The past seven weeks I had to put OO projects on hold with commitments away from home, but before I left I ordered two packs of NWSL 20” On3 wheelsets for trial.

When I was briefly home in the middle of those weeks I found the wheelsets had arrived. These are their 7801-4 wheelsets, made of nickel plated brass with their 110 tread. In OO these scale out to 31.7″ wheelsets, just a bit under the 33″ standard for freight.

They look fantastic! They are exactly on standards for American OO gauge (On3 and American OO have the same track standards) and these will work great in reproduction Lionel Amercian OO trucks as in the photo and in other applications. They would be especially good used in tender trucks where you need electrical pickup.

When you shop for these, be aware that NWSL sells two different models of On3 20″ wheelsets, one priced about double the other per package.

The wheelset question is a great big puzzle at times for the modern OO gauger, and I am very glad to have the NWSL wheelsets on the table as an option. I will be purchasing more soon.
