In March 1943, the photographer Jack Delano made a remarkable journey across northern Arizona on the main line of the Atchison, Topeka and Santa Fe Railway. He was working for the federal Office of War Information, documenting the massive work railroads were doing bringing troops and war materiel to both the European and Pacific theaters. In the process, he gave us images of small-town Arizona stretched along the railroad and U.S. Route 66. For example, above is downtown Flagstaff seen from the old depot looking across "the Mother Road." Flag's population was about 5,000.
Between 1941 and 1944, American railroads carried 83% of the increase in all traffic, along with 91% of all military freight and 98% of military personnel. Pullman put its thousands of sleepers into the effort and built thousands more troop sleepers and kitchen cars. The Santa Fe through northern Arizona, a critical route to the West Coast, saw a 175% spike in freight traffic. More than 1,000 cars a day went through the Albuquerque division headquarters of Winslow, with its 33-track yard and massive roundhouse and shops, along with passenger and troop trains.
The Southern Pacific through southern Arizona, including wartime Phoenix, saw similar challenges. But it didn't have a Jack Delano to document it.
