Union Pacific

Union Pacific
Nevada (Meadow Valley Wash)
May 1, 1982




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.
