Ran across the link on a genealogy website. I didn't do a lot of looking around, but it could be of interest to those folks modeling various kinds of rails in Brooklyn. I did look at the Subway map from 1908 showing how to get to Ebbet's Field from 1908. Pretty interesting. Maybe some of you can get some good out of the site.
