Nevada (Meadow Valley Wash)

Union Pacific signaling practice on the Salt Lake to Los Angeles line normally used color light signals like these for block signals, with a pair of widely spaced searchlight signals for interlockings (similar to Erie Railroad practice). On the left is one of the warning signals for track vehicles; this particular signal is showing clear at the moment.
