Thanks very much for asking. I double-checked the catalog and the product locator and I did not see the option to order 20-xxxxx-2 versions, so I assume the versions with scale wheels are uncataloged?

Or,,,,,,,not cataloged at all because they have not been "redesigned" for 2-Rail, as the F Units were. Thus, they are NOT AVAILABLE in 2-Rail.
