We're looking east at the signal bridge at Virginia Crews, just over a mile east of Iaeger. I'll go out on a limb and say this is one of the oldest, if not the oldest piece of N&W signal infrastructure still in service at close to 100 years old. This was originally part of the catenary installed when the N&W extended electrification to Iaeger. It's the only known example still standing, at least to my knowledge.
