I was thinking of lowering the train a bit and creating a ramp of sorts... in my city there is train station with such ramp, and usualy is used mostly for loading military veichels on trains or unloading ones... so i will try to create this vibe to it...
something like this ramp

usualy they would use also this type of Ramp - but I don't have space or the layout for it

The images are not from my town or country

I have also visited military depots with combination of both... but i will not go that much into those :D

Thinking of putting a roof on mid over the CP ...

Thinking of opening that door , so that classes that suffer from open spaces can just go around easily

thinking of making a trench thingy on the mountain side

red - sandbags
yellow - trench

I think I left it too open there...

other option is to make it part of a building that connects the main building and the bunker next to the CP but I like the idea of a trench more... so will try with that first :D

current task are:
- building town area
- shortening the distance between the spawn and the cp
- breaking the linearity a bit
- remaking of the train part
- changing the rocky bunker to be part of the HQ - to see how will look with those textures
