BNSF 976 leads a intermodal across the bridge at Diablo Canyon, Arizona as they head east on the BNSF Seligman Subdivision, through the Navajo Reservation in north central Arizona. From what I recall this slide was shot in the mid-1990s.

According to Wikipedia: Canyon Diablo is a ghost town in Coconino County, Arizona, United States on the edge of the arroyo Canyon Diablo. The community was settled in 1880 and died out in the early 20th century.

The ramshackle camp of railroad workers originated in 1880, due to the construction of the Atlantic and Pacific Railroad bridge over a large canyon named Canyon Diablo. The temporary community assumed the name of the canyon that stood in the way of the railroad construction – Canyon Diablo. The bridge construction took six months, during which many regular railroad construction workers were encamped and waiting to recommence their work once the canyon had been spanned. After the bridge was completed, construction resumed and the camp was largely abandoned.

When the railroad bridge was completed, the town quickly died. The original railroad bridge was replaced in 1900 with a new bridge to carry heavier locomotives and cars. By 1903, the only thing remaining in the town was a Navajo trading post. A new double track railroad bridge was completed across the Canyon in 1947. What remains today at Canyon Diablo are a few building foundations, the grave marker and grave of Herman Wolfe, the ruins of the trading post, a railroad siding and a double track railroad bridge.
