Railway tunnel with mushroom cultivation and a World War II bat bunker

Keep an eye.
If the negotiations with the owner are successful, the new cycle path between Laubacher Wald and Freienseen will go through one of the two tunnels.
That’s definitely a highlight!

The two railway tunnels near Freienseen bear witness to a turbulent history that goes far beyond rail traffic.
One of the tunnels was once built for the planned railway line through the Vogelsberg Mountains – but trains never ran through it. The project remained unfinished.
During World War II, the remote location was exploited: rocket parts, possibly also V1 and V2 components, were reportedly temporarily stored and guarded in surrounding bunkers.
Today, the tunnels serve peaceful purposes:
One tunnel houses a mushroom farm, the other is sealed and a protected refuge for bats.
Therefore, it's clear: there will be no passage through them – whether on foot or by bike. Nature and current use are paramount. The railway line remains history.
I was lucky on my railway line bike tour because, just as we were there, mushroom seeds and straw were delivered, and I was able to take a look inside. Great.
