Antrim PA branch switchbacks?

I know that there was a double switchback on this line north of the terminus at Antrim. The two questions I have are

Did the line go any further than the town, to some coal mines run by the Fall Brook Co near Devils Elbow, perhaps?

Was this the only place where NYC passenger trains were swichbacked?

Possible .... but not likely. The railroad as drawn on the topo dead-ends into the hillside.

I just discovered this line by looking at old PA topo maps.

Does anyone have more info?

Here's a 1946 topo map that shows the tracks from Wellsboro to Antrim:
