Interesting article! (We don't have that problem around here ) I do think I have seen a switch heater for an electric switch in town. Harold
Didn't know they were 106mm. Interesting. When I fired these, while in the military, we called them a 105. For many years, the highway department in Washington state had one of these. On the west side of Snoqualmie Pass. It was located in the vicinity of the west portal for Milwaukee Road's tunnel. But was used in a direction away from the railroad. Don't know if anything is still in service, since I-90 was completed. Boxcab E50
