There was once a two-foot gauge railroad that operated in southwestern New Mexico. My last railroad assignment was on the Southwestern Railroad. We have a branch line that serves a couple large copper mines. This is the remnant of a Santa Fe line that connected with the El Paso and Southwestern (SP) main line at the Mexican border a few miles west of Columbus, NM. It ran north from there to Deming (on the SP Sunset main line) and continued north to Burro Junction, south of Silver City. The line runs west of Burro Junction to a large mine at Tyrone. Another line branches off at Whitewater, south of Burro Junction, and serves a mining district at and north of Hurley. The track between Burro Junction and Silver City, the track between Deming and the EP&SW, and the EP&SW themselves have been taken up.
Silver City was the northern terminal of this line. The Santa Fe yard was at the far southern end of town. The railroad tracks and station are gone, but the locations can easily be seen.
The Santa Fe yard and station were the location of an interchange with a two-foot gauge narrow gauge railroad (I don't remember the name). This railroad ran north from there along a creek. A catastrophic flood wiped it out, along with the main street of Silver City. A gaping canyon up to 50 feet deep was left in its place. The city gave up fighting nature. A parallel street became the main business street, and the front sides of the main street buildings became the back sides. In place of the main street and little railroad is now a city park named "The Big Gully" (I'm not making this up)!
The little very narrow gauge continued on north of Silver City to serve the gold mining town of Pinos Altos. I think a state highway is built on the roadbed. There was a station, yard, and engine terminal in Pinos Altos. Walking around in Pinos Altos, I could see no evidence of it. BUT...if you check out Pinos Altos on Google Earth, you can see the narrow gauge right of way, station location, yard track layout, and turntable pit!
Railroads leave scars on the earth that require a bulldozer to remove. Especially in the dry southwest. And especially when seen from space.
