Right behind my house is the Panhandle Trail in WV. Old coal town that used to have several tracks running through it.

Not very long, Length: 29.2 miles, but it crosses a couple longer trails in PA.

"The Panhandle Trail crosses the 61.5-mile Montour Trail, which links to the 150-mile Great Allegheny Passage and the 184.5-mile C&O Canal Towpath for an off-road connection to Washington, D.C."
