'mystery' location #1: Looking east across elevated tracks behind PE's 6th & Main Sts. Terminal.
'mystery' location #2: Looking NNE at PE's Watts depot (E. 103rd St. & Graham Ave.), still stands.
'mystery' location #3 (with ghost): Looking SE at PE's Watts Substation. After staring and squinting a lot, suspect that "ghost lady" is a backyard incinerator or similar concrete object. Magnification of the image quickly results in pixelation, but I can't make a convincing face on the "ghost". Also, the gentleman in the photo is looking northward up the tracks, not at "her". And it's not Halloween.
