December 2015 updates
Returning to this area I wanted to see if I could find more of the railbed before it becomes private property. Only a small section beyond what I already photographed could be seen. Most of this branch is heavily overgrown.
Pictures from the O&W Northwest Junction
When I was photographing the O&W Northwest Junction, this railbed was spotted while looking at the switchbacks of the O&W trackbed. At the time this was listed as unknown, but now with the valuation maps of the D&H (Erie's Jefferson Branch) it showed this railbed connecting to the O&W's track. These pictures were taken in 2012 and most are on the O&W's page, I am presenting them here starting from the O&W side to show the railbed as much as possible except for the section that is now private property.

it connected to the NY O&W switchbacks.
Pictures of the NY O&W side and what was called the "unknown railbed" are on this page. The valuation maps shows the D&H connected to the first switchback of the O&W's branch line. "Part 2" of that page shows this connection, but due to private property, the entire branch connection cannot be seen.
