Data from DeGolyer, Vol 78 pp. 16+. See also Mississippi Rails' account of the NU&R at [], last accessed 7 August 2013. Works number was 58496 in June 1925.
Originally ordered by the Central Cespedes from Baldwin Havana's stock, the oil-burning plantation Consolidation #3 was instead sold to locomotive rebuilder/reseller Birmingham Rail & Locomotive. The engine languished on BR&L's books (but in Baldwin custody) for an exceptional nine years. During that period, the 3 was converted to coal firing in 1931. Baldwin removed the oil-firing equipment and sent it to the BR&L. This was in preparation for delivery to the Tuskegee Railroad
Finally, on 13 April 1934, BR&L found a buyer in this Louisiana short line. According to Mississippi Rails, the NU&R traveled for 20 miles (32.2 km) over rolling terrain on 52 lb/yard (26 kg/metre) relay rail (rail reused after service elsewhere) and 35 lb. (17.5 kg/metre) new rail. By the time the 3 reached the railroad, however, it had shrunk to 6.5 miles (10.5 km).
Later the engine went to the Central Maceo in Cuba. When the 1959 Revolucion resulted in the expropriation of private property, the central was renamed for Antonio Maceo and the 3 2was renumbered 1756.
