The Operating Freight Station No. 356 was another accessory that Lionel produced that used a vibrator in the base, in this case. to move baggage carts in and out of the station. Some issues would have six adhesive posters that were to be placed on the structure. Other variations have to do with the carts that sometimes had lithographed baggage loads. The last variaition (D) had a LIGHT GREEN roof and came with no posters or baggage loads. This accessory was produced from 1952 until 1957. Dimensions: 12" long, 3-1/4" wide, 5-1/8" high.
