The Lionel Rio Grande FA A Unit No. 221 was produced in 1963 or 1964, and this engine’s body would have the coupler pocket in the front filled in and was mounted on a sheet metal frame that had a solid non-operating rear coupler. Examples have been found with both a forward only and two-position directional unit. Not equipped with Magnetraction, but did have a light and the power truck had one traction tire on the right rear wheel. Note that the ornamental horn has been removed from the roof and the mounting pocket has been filled in. There are no variations.
