That map came from the Amsterdam quad on historical.maptech.com, and was printed in 1895 (below). You can see that the route as drawn was a little crude. They didn't have the aerial photos that later maps were drawn from. I also noticed the route of the FGnJ trolley from Hagaman to Rockton. No sign of it south, though.
