    I've been using ARM 109 Cumbers roadbed for some time now and it's perfect for my old-time logging railroad. This ballast lays down well and adheres to the layout easily with a white glue & water mixture. I love its color and it looks so natural on my railroad! I have ordered it several times over many months and each bag I receive matches the previous bags in both color and size exactly. An excellent product!!! Thanks for your attention to detail.

    Just what I wanted!

    I am doing a Southwest Colorado Mountain model Railroad. I had used some other ballast material from a major distributor that I felt wasn’t natural looking or the right colors. ARM’s is spot on. Only wished I had used it on the other part as well.

    Cumbres and Toltec Brown Ballast is a form of decomposed granite aggregate that is often chosen as the decomposed granite ballast used to support the rails in railway construction. As with roadbuilding, granite aggregate is popular with track layers due to its strength, durability, and excellent drainage-promoting qualities.

    Granite is the most common igneous rock (rocks formed through the cooling and solidification of magma or lava) on Earth. In the case of granite, it originally crystallizes below Earth’s surface, where its slow cooling allows large crystals to form. You may have seen granite take shape as some of America’s favorite sights like Yosemite Valley or a few guys on Mount Rushmore. Granite has also been mined and used for daily applications for thousands of years, from ancient hand tools to modern-day countertops.

    Cumbres and Toltec Brown Ballast as a crushed stone form is used as a pavement building material. It is used on driveways, garden walkways, bocce courts and petanque terrain and urban, regional, and national park walkways and heavy-use paths. DG can be installed and compacted to meet handicapped accessibility specifications and criteria. Different colors are available based on the various natural ranges available from different quarry sources, and polymeric stabilizers and other additives can be included to change the properties of the natural material. Decomposed granite is also sometimes used as a component of soil mixtures for cultivating bonsai.

    While DG is most commonly used for paths, driveways, garden trails, and as a xeriscape ground cover, it can also be used to create smooth visual transitions between formal garden and wilderness. One of its advantages is that it breaks down, so any DG that migrates into a lawn or planting beds does not cause problems the way gravel does. Lining a path or patio with a black metal strip (which will disappear if buried low enough) will help keep it in place.

    Track ballast forms the trackbed upon which railroad ties (sleepers) are laid. It is packed between, below, and around the ties. It is used to bear the load from the railroad ties, to facilitate drainage of water, and to keep down vegetation that might interfere with the track structure. The ballast also holds the track in place as the trains roll over it. It consists of crushed stone. The term “ballast” comes from a nautical term for the stones used to stabilize a ship.
