Try around NY, Boston and east coast in general,
especially the metro
regions. Many of the rails have been abandoned over the last 50 years
and are being removed infavor of many uses from trails to roads.
If they've been abandoned for to long it takes a lot of work to get them
back into condition to run trains over them. While we've had a lot of track
ripped out around here, they've also reopened a fair amount of it.
