Kohnstein near Nordhausen, Harz.

Not rail related? I don't think so - This shows the former south entrance of Tunnel A of the Mittelwerk factory in the Kohnstein. Two railway lines went through the whole of the mountain for supply of the underground factory where V1 and V2 were build in 1944/45!
See strs_hsb_0073 for remains of these lines.
