This add-on includes models of two series of GN cabooses, a 30' wood cupola caboose and 30' steel cupola caboose. The wood bodied cars were built from 1941 to 1945, the steel cars between 1941 and 1951, all in GN's own St. Cloud shops. Both were numbered in the X200 series.
Nine cars are included in this add-on, four wood body and five steel body cabooses. Five cars come in GN's striking classic red and black caboose paint scheme, with three different lettering styles included: block lettering with yellow font, block lettering with white font, and the later lettering scheme with italic slab serif font and radio symbol. Also included are the GN Big Sky Blue and finally the BN green versions of these cars.
The cars in this add-on are ready to run with custom sounds and couplers with connecting air hoses and a passenger view on the platform of the car. The autonumbering includes roster numbers from the real GN X200s, and also correct assignment of the Safety Slogans to the road number of each car.
