Voice On The Karwendel Railway (mittenwaldbahn)

A voice and the sound of a train can be heard not far from Seefeld in the direction of Scharnitz! Does anyone know what it could be? Best regards!

 

I remember hearing about German steam being TSG's next route, maybe that's the leak?

 

Thanks for the answer. I'll have another look later to see if it sounds like a steam locomotive

 

The only nearby railway line is the unterinntalbahn from Kufstein to Wörgl. Could be very possible that they have created a background sound for it. I dont think its a leak or something

 

Thanks for the comment. But what would the voice be for?

 

The noise sounds like the release of a brake. I can't understand what the voice is saying.
