How tf am I suposed to get up the firs part was ok but now like???

all red like where is the way?

What is gray?? is that jus that even the radar cant tell?
[Update]
I have found the grip upgrate for the tracks but even when I got up to the tower I found there is no way to go up further as the walls are vertical or inside as there are no openings then I got stuck under the tower betwen 2 of its walls and had to reset anyway I heard some rumors about grapling hook but it is definitaly not the one where you can pull items and its permanent because that one can't pull you at max it can stop you from going or falling further so you can use it as in Tomb raider sections where you swing across a hole section or idk I will try to keep looking for some way to defeat the climb so I can finish my delivery to B4B3L. I will defeat verticality!
(It may be posible with the stuf where if you put something in superposition inside and have it covered you will fly.)
