Wagon Mound. The former Atchison, Topeka, and Santa Fe Railroad semaphore signals on the BNSF Railway Raton Sub are perhaps some of the most iconic signals that are still active today in North American railroading. While they are slowly being replaced by newer signals, there are still a significant number populating the area. On Thursday, April 14, 2022, Webb Rail's former Northern Pacific Railway Budd built Pullman dome/sleeper 313 (WEBX 801044), former Northern Pacific Railway Budd built dome/coach 549 (WEBX 801045), and former New York Central Railroad Budd built Pullman obs/diner/sleeper "Babbling Brook" (WEBX 800007) pass by the interlocking at 724 that controls the East Wagon Mound Siding in Wagon Mound, New Mexico on the Amtrak Southwest Chief (Train 4). While the oldest of these Private Varnish cars was built in 1949, the signals are even older.
