It would appear the the signal control box at the west switch of Tennessee Pass has moved around a bit over the course of its life. You can pretty clearly see "Arvada" painted over on the box. And, if you look even closer, it appears "Arvada" was painted over something that starts with a "P". Even closer examination reveals what appears to be an "A" and an "L". That being the case would mean this box also spent time at Palisade near Grand Junction.
