NNG The Ski Train "Flasher"

My daughter and I were regular riders of the Ski Train. I'm guessing about ten years ago, one of the car attendants pointed out the "flasher" to our car. Since then I think my daughter and I have seen the "flasher" on both ends (up & return) of all of our trips except one. He was the source of several discussions on the train.

Now to explain: The flasher lives near the Lowell Blvd crossing and shines a high powered search light on the train as it passes just East of Lowell. I don't know if he also flashes the Amtrak trains or not. Over the years I think he has acquired a better light. It's a hand held unit and when it's not too dark I've seen him standing on his back deck with the light waving to the train. I've also seen some vintage army equipment around his garage.

I'd appreciate knowing more about the flasher without revealing any information that the "flasher" might want to protect. How long has he been doing this? Does he also flash Amtrak? Does he have any Ski Train stories to share? Do any other forum members have flasher stories to share?
