Litchi can do much more.
Full way with Litchi waypoints camera manual
Starting at -20 alt just over horizon so it was not possible to go down more
The challenge was that the track led on the other side of the hill so I had the path behind the top of the hill and had to take care just not to loose the signal. I did make a testdrive with camera to the front before to make sure not to crash into a tree, but everything was fine I did not have to make any adjustments. I calculated the alt on google maps before.
This train goes only 3-4x a year so I had to take weather as it was, next year I will modify the path to stay a little more away from the train at the beginning I was to near for this altitude.
