I wasn't the only one to be excited. This chap had stopped his car and was taking a picture. When I told hubby, he was incredulous. According to him, there are no such things as trainspotters in America. My guess is that they exist but they're different, a little like twitchers, who tell each other about the arrival of some rare bird and rush off to see it.
* this is a little poetic licence. If the wind's in the right direction, we can sometimes hear faraway trains from our house, with their lugubrious whistles. All freight trains these days of course. The station in Olean is now part of the Community College. And some of the freight trains are extremely long, so I was lucky. This one was just an engine.
