The operation is on the former Northampton and Bath trackage in Northampton, which is just north of Allentown PA (or a little more than an hour from Scranton). As for when they operate, no one I know has an idea. They used to park an engine by a truck dealer on one of the roads through town (can't remember the name) but that was several years ago.
