Data from "New Locomotives, Manila Railway", The Locomotive Magazine, Vol XV (15 May 1909), pp. 95.
Although the Americans had taken over the Philippines from Spain following the Spanish-American War, there were still many British-owned concessions in the islands. Among them were the Manila Railway, which succeeded the Manila Railroad established before the war. This new holding company was formed in 1906 at the same time a New Jersey-based operating company was also created. The railway continued to buy British for some time, as these well tanks indicate.
The Manila Railway was bought by the Philippine government in late 1915 and retitled the Manila Railroad.
