Wall on left has been airbrushed with Vallejo ______, then individual bricks painted with ___ and ___; the wall on the right has had talcum
powder “mortar” applied.

Working With 3d Printed Acrylic Plastic Parts

The 3D printed parts are an acrylic plastic. While strong, these are not as strong nor as flexible as the engineering plastic or styrene you
may be used to working with. Carefully remove parts from attached sprues. Parts should be carefully washed with isopropyl alcohol before
painting. For fragile parts, such as the delivery pipes at the tank car loading platform, lightly coat the 3D printed part with a low viscosity
CA adhesive to strengthen the part. Examine the drawings, and drill holes where required. Glue 3D printed parts together with CA
adhesive. It is recommended that all the 3D parts be sprayed with an undercoat of flat black acrylic modeler’s paint such as Vallejo NATO
Black. These parts can have undercuts and recesses, so be sure the spray penetrates all areas.

Working Corrugated Metal Siding and Roofing
Included in the kit are sheets of metal foil embossed with scale corrugations.
Handle these carefully. It is recommended both sides of these be air-brush painted
with a flat light gray primer. After this thoroughly dries, cut individual pieces of foil
following the included template, using a NEW, SHARP blade. Weather the siding
with a very thin wash of Vallejo NATO Black, and when thoroughly dry, “rust”
with Rustall. Note in the prototype photos on the website, the roof was heavily
rusted, while the sides were much less so. Glue the corrugated metal to the wood
framing using thinned Walther’s Goo (1-part Goo to 1 part acetone.).

Working With Site And Building Bases

The kit is designed to facilitate the assembly of some of the separate structures on individual bases prior to installing on the layout. These
bases are thin laser-cut plywood. To increase the dimensional stability of the base as well as make things easier to handle during
construction, it is suggested these bases be glued to a substrate of larger dimensions made from 1/8” tempered hardboard. For other
structures (such as the various tanks) individual bases or pads are provided which are to be installed on the layout prior to installing the
structure, to allow leveling of the base or pad and the installation of basic scenery materials adjacent the base or pad prior to installing the
structure. After gluing in place, it is suggested these be painted the same color as your “earth” base color. For the prominent
still/condenser/boiler/tail house complex, a base incorporating all these structures is included. It is suggested basic scenery be installed on
this base prior to fitting the structures to the base, then the base with structures be installed on the layout. This process is described more
fully in the “SITE” section of the instructions.
