[QUOTE]Originally posted by PaulB: [QB] Nice Photos. I've had Ray in the dining car on the Sunset before-he has a unique wit. I don't know about signals freezing, but switches can freeze if the heaters are malfunctioning. Switches have lots of moving parts, and if they freeze it becomes difficult to impossible to move these parts. So, there are heaters for each switch. These may be electric, or propane if the switch is out in the sticks. It may be that relays or other controls for the signals froze, but I think this is rare. Most likely the switches froze.
