Tannin extraction plant model

My next model is a tannin extraction plant.  This plant will have a number of structures and details so it will occupy me for a while.  The tannin is extracted from tree bark and is used by tanneries.  The first structure is a bark shed (no dogs involved).

This shed is located track-side for delivery of bark by rail car.  There will be a ramp to allow for the bark to be dumped in the wide front opening.

The rear view shows the opening where the bark will be transferred to the chipping shop behind the bark shed.  The bark shed has a corrugated metal roof. The walls were built board by board.

Above is a view of the bark inside the shed.  I gathered the bark from a dead evergreen tree on my property.  I broke the large pieces of bark into small pieces.

Pallet shop truck

I have scratch built an old style truck for carrying pallets.  A few parts are commercial.  They are the wheels, the pallets, the front grill, the seat, and the steering wheel.  The rest are mostly made from wood and card stock.  The seat is an old solid wood passenger car seat from an old Labelle kit.

The front bumper is a thin piece of aluminum.  The headlights are from a plastic sprue.

A reasonably easy build.

Now I will move on to another structure.

Pallet company complete

The pallet company is complete.  The building includes the offices, living quarters and pallet storage.
On the right side is a covered area where the pallets are constructed.  Two workers are constructing pallets - one is cutting the wood and the other is nailing the boards together to create a pallet.

The roof shingles are by BEST, the windows are by Tichy and I do not recall the manufacturer of the doors.  

Against the wall are a work bench and some shelves.  There are some wooden barrels containing nails.  I constructed four saw horses from strip wood which were difficult to build as they are very small and my hands are shaky.  There is a pile of wood on the left to be used for the pallets.  I added sawdust on the floor under the sawhorses.  

There is a pallet stack on the rear platform.

What to do next?????
