Why Soldier Summit looks going downhill when you are going uphill?

Some are saying what I am going to say here is just an obsession. But there is something weird indeed. I don´t think this has been discussed here before, but my quest is addressed to the scenery specialists, which I am not. So here I go.
When you are driving a loco in Soldier Summit going "uphill", the sensation you get is that it is going downhill. This only happens in Soldier Summit between the about 20 routes I have in my collection. I posted about this in DTG TS2015 forums:

Originally I thought the Soldier Summit syndrome was caused by some wrong value in the cabviews .bin of the route locos.
Last week I have been making mods for four of the steam locos I have (K4, Berk, Northern and FEF-3), so you can see the far away rails in front of your loco thru the internal cab view front windows.
So I checked if the cause of the SS syndrome was in those .bin cabviews. Finally I determined the phenomena had nothing to do with those.
So the cause of the downhill sensation was the scenery and not the locos cabviews.
This is my question: Are you aware of a .bin where you may change the values for the direction of the vector of the external scenery view in a particular route and how to find it?
