The Minneapolis & St. Louis Caboose No. 6059 was produced on a Die 4 body with AAR trucks that had either one disc or solid coupler. Production started in 1961, and ended with the last year of the Post War Era: 1969. During this period there were several variations that occurred. Variation A is has a RED painted body over GRAY plastic. Variation B has a flat RED body that is not painted. Variation C is a BRIGHT RED color, and Variation D has an unpainted MAROON body.

This car was issued in many catalogued and uncataloged sets and because of this, it is difficult to find with a box. The only boxes that exist are from 1962 in set No. 11288 that is stamped "6059" on the end, and in 1969, in a checkerboard Hillside box labeled "6059-50" on the end.
