One of the things that have been under way for a long time is the cargo route(RP'ed) from the outside and into the bunker. I have held back because lots of details and sections were still unfinished. But I put in an effort recently to finally get it somewhat finished 
It all starts down at the foot of the mountain:
Disregard the collapsible blocks. Still planning/testing the road network etc. that will eventually connect the bunker up to the rest of the base(s).
The bunker doors are animated with Drawbridges using the same setup that I used back in 1.6.4 TPPI:
The Garage:
Parking space for Container Trucks(it makes more sense when there are containers on the back
). Plan is to have them placed around the base/farms to simulate cargo being transported around.
The wheels are made with Armourer's Workshop.
Personnel transport:
A few vehicles for getting around.
Transport control/office:
To travel further into the bunker:
Couple of elevators. I tried doing them with movable frames, but could not achieve the visuals and effect that I wanted. So replace them with static cosmetic ones instead.
At the top, a small trip outside is required to cross a ravine/stream:
The cargo route also joins up with the staff entrance which comes up from the office.
Seen from the outside:
Bridges have been retracted and doors shut in this pic(Drawbridges and various redstone circuits).
Inside on the other side:
The hallway on the right is meant for staff. It leads to the bunker centre atrium thingy.
The cargo trucks continue in and down another set of elevators:
Below:
Containers are picked up by the overhead crane and taking further into the base.
(I just realised that I forgot to build a truck here, which had just been unloaded/waiting to be loaded...)
The containers are then taken into the cargo unloading dock:
To be continued...
