Among several types of Baldwin locomotives ordered by the Cuba Central Railways Ltd., there were 18 4-6-0 locomotives which were built between 1904 and 1912. Although they were officially listed as freight locomotives with a driver diameter of 56 inches (1,422 mm), it seems like they were also used in passenger service. With some differences in detail, there were numbers 41 to 49 built between 1904 and 1907 and numbers 50 to 57 built in 1911 and 1912.

They were classified by Baldwin as their type 10-30 D. The first three received tenders with 3,000 gallons of water and eight tons of coal and all others received tenders with 3,500 gallons of water and the same amount of coal. Most had Stephenson valve gear, but the last three got Walschaerts valve gear. Only No. 54 got a Baldwin smokebox superheater. Numbers 50 to 57 later came to the Ferrocarriles Unidos de la Habana and were numbered 61 to 68.
