    I have not yet received my order

    I ordered on Dec. 2, 2019. My first call to ARM I was told that it would ship by Dec 17th. On my next call, I was told the product was backordered. A subsequent email asking about the order went unanswered. If I don't hear something in the next week, I will cancel the order. I do wish there was better communication regarding order status.


    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.
