|Described by Lionel in the 1950 catalogue as "by far the most unusual, most facinating of all Lionel roadside accessories". Has three separate actions: uncouples car from train, dumps coal from car, and uncouples car from ramp. When used with the 397 coal loader, this makes for some real railroading fun. Included is the 3456 operating hopper car - the only car from the Post-War era that will work with this accessory. Components ncluded a three button 456-100 controller, a 3456 operating hopper, a 456-83 maroon plastic receiving bin, two 456-85 coal pin mounting posts, a 456-84 coal bin door, and a bag of 206 coal.
