in 2008 a high speed train meets 20-30 sheeps in a tunnel with 230 km/h here. it was a real damage then https://de.wikipedia.org/wiki/Eisenbahnunfall_im_Landr%C3%BCckentunnel

the sheeps were in a corral near the railway. the conclusion was that dogs hunt the sheeps over the fence and into the tunnel. this was the time when the wolf found new land very quickly and the wolf fuckers were singing his hym of praise every day. they never found the dogs but never looking for the wolf because this bad news was nothing that fits into the success story.
