Between Albuquerque and Raton Pass (on the New Mexico-Colorado state line) I counted three bastions of Union Switch & Signal style-T2 upper quadrant semaphores on our journey over the former Santa Fe in Vista-Dome Silver Splendor.
I watched the blades drop from the vertical as we passed—a scene I’d not witnessed for many years.
In 2018, these signals represent the last large collections of active semaphores on any North American mainline.
The Style T2 was detailed in my book Classic Railroad Signals in a sidebar titled ‘Sante Fe Semaphores Survive in New Mexico’ by John Ryan and the late John Gruber.

Railways can offer tremendous technological contrasts. Among my photographic themes is juxtaposition of the oldest technology along side the most modern. When I made this image, there was roughly 60 years between development of the signals and the locomotives.
I made this image during an exploration with Mel Patrick of the former Santa Fe mainline across northern New Mexico and eastern Colorado. At that time BNSF still maintained many of the old Union Switch & Signal Style T-2’s dating from the steam-era.
The Union Switch & Signal Style T-2 was featured in my book Railroad Signaling published by Voyageur Press. Here’s an except from my text: “US&S’s T-2 is a three-position upper quadrant type with a top of mast mechanism. Typical semaphore height measured 22 feet 6 inches from the ground to mechanism.”
Traffic on this line was relatively light, with only Amtrak’s Southwest Chief and a couple of BNSF freights daily. Then, as today, most of BNSF trans-con freight was routed via the Belen Cutoff (through Abo Canyon) to the south.
