The Lionel Rio Grande FA A Unit No. 222 was shown in the 1962 advance catalog. This engine’s YELLOW painted 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. This diesel would operate only in the forward direction, therefore no directional unit is installed, and the slot for the control lever on the top has been filled in. Not equipped with Magnetraction, but it 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. There are no variations.
