Hey folks -
For those that don’t know me from the Model Railroader General Discussion forum, I am a pilot for both the military and a corporation.
I flew for the corporation last night, and did a little railfanning from the air.
Last night’s flight took me to Roanoke, VA, and on the way out of there I departed runway 24 and made a lazy turn to the east so I could get a glimpse of the former Norfolk Western (now Norfolk Southern) yard and engine terminal. I was amazed to see that there was still a turntable there, and there were TONS of locomotives sitting there to be worked on. Anyhow, as I was looking down into what was a relatively dark yard, I saw dozens and dozens of what could only be described as blue/white strobe lights. It looked like fireflies had invaded the yard! I was wondering if anyone with some knowledge of the prototype can tell me what those lights were and what they are used for. Thanks in advance!
