Things I couldn’t do without:
1. Steel mill
2. Urban area with tall buildings
3. Ability for continuous running. I work a real job and don’t care to make model trains another job.
4. Trackage in the streets.
Since this is a fictional bit of history, I can bend it whatever way I please. The Northern Central Railroad is recreated here as is the Joppa Iron works that was an actual company in the early 1800’s on the banks of the Gunpowder River in Baltimore County. At one time I owned a home close to the original site – we even used to dig up old bits of slag out of the dirt whenever we were planting anything. Another clue to a colonial iron site was the absence of any old trees in the area.
I am not picky, so as long as I had these items, I was just fine.
