SubTerrain FAQs

  • What is the difference between Incline Starters and Incline Sets?

    Incline Sets are a packaged set of foam inclines that create a pre-determined 2%, 3% or 4% inclined run within a specific distance. Incline Starters are packaged with several identical 2%, 3% or 4% foam inclines, each beginning at 0%, and are used in conjunction with sets and risers to simplify the construction of even the most complex layouts.

  • Is it true that SubTerrain foam products will not crumble or fall apart?

     Yes, it is true. SubTerrain® foam products are molded at a higher pressure and temperature than other expanded foams. It will not come apart. Other foam products are not suitable for layout construction, because they may literally crumble and fall apart while handling and cutting.

  • Why is SubTerrain foam made with expanded foam?

    We needed a foam product that could be cut quickly and neatly. The Hot Wire Foam Cutter smoothly cuts through SubTerrain® foam and emits no toxic fumes! It’s actually quite fun to use the cutter with our foam. NEVER use the cutter with any other foam product other than SubTerrain®. It could emit toxic fumes.

  • Can I use the SubTerrain Hot Wire Foam Cutter with other kinds of foam?

    No, never. It could emit toxic fumes.

  • How do you mount a tortoise switch machine under the track if you are using SubTerrain?

    Cut a notch in the Risers and install a hard board to support the mechanism. Cut a hole in the base for installing and servicing the switch machine. Complete the installation according to the manufacturer’s instructions.

  • Are your Foam Sheets extruded foam or can they be carved?

    Our Foam Sheets are expanded foam, not extruded. They can be quickly carved with a Hot Wire Foam Cutter, Foam Knife or other hobby knife.

  • I want to build a layout based on a picture I have but don't know where to begin. How do I do the configurations, etc?

    The easiest way to do this is to download the Atlas RTS track planning program to your computer.  This is free and will allow the user to design a track plan in a very user friendly way.  http://www.atlassrr.com/righttrack.htm

    Degrees of inclines can be programmed in and then the product needs are easily calculated for you.

  • How do I add a 'switchback' to my track layout?

    Use the same modeling techniques for building a switchback as you would for building any track area.  Start by creating the incline base with 1" Foam Sheet (ST1424).   Construct the support for this with 1/2" Foam Sheet (ST1423), apply 1/2" incline pieces (ST1410) for the track, fill the contours with newspaper wads, cover with Plaster Cloth (C1203) and apply terrain products as usual.  In essence, it is just constructing an extreme incline.  Modeling skills and experience will determine the level of detail.

  • Are you planning to make riser kits for O scale? Or any with a higher elevation? I seen how great your risers & inclines work with HO and wish I could utilize the risers with my O scale layout I am getting ready to build.

    At this time we do not have plans to make either O scale risers / inclines or any with higher elevations.  Although, you can use the riser / incline kits for O scale by gluing two HO scale risers / inclines side-by-side.  You can also build up your elevations with multiple risers and inclines placed on top on one another.   At this time our inclines only go up to 4 1/2" and our risers to 4".

  • Would it be possible to order six or eight exactly 3.5 inch foam risers?

    Unfortunately we do not have 3.5 inch risers.  To Accomplish this you would need to install our 2", 1" and 1/2" risers on top of one another to get up to that height.  Each package contains 4 each and each piece is 2.5" wide x 24" long.  Of course quantities to purchase will depend on the length you need to go. 

     

  • What is the difference between O and On30 scale? What scale track, risers and TrackBed are compatible?

    On30 scale is O scale trains with narrow trucks on them ('n' stands for narrow guage).  They WILL run on HO track, risers and TrackBed. 

    Here is some basic information about the scale....Modeling in On30 involves using HO guage track and mechanisms with O scale (1:48) models to represent 30" narrow gauge in O scale.  Outside of the US this is sometimes called O-16.5.  O scale is slightly different (1:43 / 7 mm to the foot, or 1:45) in other parts of the world.  Modeling in O scale means that your models will be 1/4"= 1 ft. scale.  It's important to remember that your buildings and figures will be roughly twice as large as HO.  On30 scale modelers use HO gauge track to represent 3" guage in O scale.  This lets On30er's fit more layout in the same space as regular O guage.
