This low-numbered Consolidation never strayed from the GW. Its scrapping came almost 50 years later in March 1951.

See Locobase 4811 for a description of this Colorado sugar-beet railway. The 2 was in every way a considerable step up in power and flexibility. The taller drivers allowed more speed (although clearly a relative advantage) while the larger boiler and grate together with the larger cylinder volume led to increases in tractive power and steaming capacity.
The 2 was scrapped in March 1951.
