Introduction
The Grand Valley Layout Kit models a 4' x 8' HO scale layout complete with inclines, mountains, creeks, tunnels, bridges, roads and
landscape. To aid in assembly, the track plan is printed on the Foam Base and contours are printed on Profile Boards.
Before beginning, collect the additional household items necessary for building the kit (listed under Household Items Needed). We
recommend purchasing a Low Temp Foam Glue Gun (ST1445) and Low Temp Foam Glue Sticks (ST1446) and Hot Wire Foam Cutter
(ST1437). These tools make building the Grand Valley Layout Kit easier and more efficient. Find them at your favorite hobby shop.
When building Grand Valley, know that mistakes can be fixed. Woodland Scenics Systems are designed to leave room for error and
modelers can go back and fix problem areas.
Risers and Inclines are included, along with a pre-printed track plan. Risers and Inclines are part of the SubTerrain Lightweight Layout
System®. They elevate the track above the base of the layout, making it easy to add ditches, creeks and low-lying areas without cutting
into the base. Inclines add predetermined grades to the layout, so the train can climb and descend hills easily, without you having to make
complicated calculations.
Instruction Notes
Before beginning each section, read through the steps to understand the modeling process. Illustrations are included to demonstrate the steps.
As you cut the Profile Boards and Foam Sheets, keep all scrap pieces until you are done with the project. Scrap pieces will be used in
assembly of the layout.
Kit Contents
We used the Atlas Grand Valley Track Pack #589 (ST1183) with the Grand Valley Layout Kit, but you can use another brand or
type of track, if you prefer. Refer to the list on the back of this instruction booklet for track requirements.
NOTE: When assembling track, it is not necessary to center on the Risers. Test train to be sure it runs properly. If running a long line of
rolling stock, verify clearance around tunnels, bridges, rocks, etc. and adjust accordingly.
