You may wonder why bother with going to the downtown and industrial areas of a major city, with the attendant parking problems, traffic, chance of getting in trouble for trespassing, slummy neighborhoods, vagrants everywhere.. There’s plenty of other places to go railfanning.
Why? More. Trains.
When you can watch more than one main line, you see twice the trains. At least. And with a few small-town exceptions like Folkston, most of the places where major rail lines come together are in the cores of cities. Often these rail junctions are the cores of our cities.
So, yeah, it’s about volume, volume, volume.
