Lionel added remote control couplers to the 814R reefer in 1938 to create the 2814R refrigerator car.
Two versions were made; both are shown on this page. The earlier white with blue roof is more common than the later rubber stamped car.
White with Blue Roof and Nickel plates 1938-40
2814R Flat white with tuscan roof and rubberstamped lettering.
