Data from DeGolyer, Volume 66, pp. 344+. Works number was 55910 in December 1922.
Wood-burning plantation Prairie tanks of this size in Cuba would have probably run on the 30" (762 mm) gauge. But virtually no Baldwins were bought for so small a gauge in Brazil. The sugar engheno that operated this engine was located northeast of Rio de Janeiro near the coast.
