No. 287 was a 2-6-0 built by Alco/Cooke in 1906 (B/N 39198) as Isthmian Canal Commission (I.C.C.) #287 (Panama Canal Railroad). It was acquired by the Alaska Engineering Commission in 1915.
It became part of the Alaska Railroad in 1923 and was scrapped in 1947.
On this SD card you should find images of locomotive 287 and of my great great grandfather Benjamin Franklin Eidenier, who was the engineer of 287 between 1907 and 1916. He was also an engineer for the New York Central in Western, NY. After his canal work, he went to Costa Rica, Chile and finally was an engineer for the Cerro de Pasco Railway in Peru. He never went back to the U.S. after 1911 and died in Lima, Peru in 1924. Quite a guy.
