The loading docks which come with the ITLA loading dock didn't feel right to me— they seemed more like truck loading doors than railcar spots:
To fix this, I raided my "personal hobby shop" and found some old DPM modular wall sections:
After cutting, fitting, bracing and gluing I used some Army Painter Chaos Red to paint the bricks, followed with a wash of AK Interactive Medium Gray for the grout. (I specifically went heavy because I knew I was going to come back with more weathering and this wall would be hiding underneath the rest of the building.)
When I was happy with the brick, I came back and added some Evergreen styrene strips in order to model the cement posts seen inside these brick curtain buildings.
This also did a good job of hiding all the wall section joints:
Been pretty happy with how this is coming out:
The task of adding all the windows, doors, glazing, floors, and roof comes next— along with planning the final assembly and any lighting details.
The dock is also screaming for some lights over the doors:
