The 3859 dump was introduced by Lionel in 1939 and ran through 1942. The car was always red with a black frame. This car dumps its load of simulated coal at the push of a button, and is a perfect complement for Lionel’s 97 coal loader.
The only variation is the type of frame and couplers. This car came with either the type 3 frame and automatic box couplers or the type 4 dished frame with solenoid actuated simulated knuckle couplers. Neither variation is difficult to find, but the later car runs better.
