Works numbers were 32984-32985 in September 1908.
These Prairie tanks were bought to help build the T-P, which was begun in 1908 and completed in 1912. The Tientsin-Pukow loan contract signed between foreign investors and the Chines government in 1908 were so unbalanced, and the contracts so incompetently managed, according to Meribeth Cameron, that "'Tientsin-Pukow terms' became synonymous for undue leniency and insufficient care for the safety of foreign investors."
The railroad covered 627 miles (1,009 km).
