Going north from Fulda to Kassel on entering the tunnel ruuning from 37 km to 34 km south of Kassel, the "end view" appears quite close for a moment and then vanishes until a distant end view appears at about km 35. 7 km south of Kassel, the end appears before even entering the tunnel. This latter may be GPU dependent, but not the former i would think. I have replicated the former on a second run from Fulda to Kassel in an ICE. thanks for your forbearance if these are uncorrected known glitches.
