Hi Zwibby,
They are slow motion switch machines used for model railroads. You would take them and place them underneath your train layout (called benchwork or a baseboard) so they are hidden from view. With some simple switches and an electrical feed they can be made to work. This particular product does as it's name - moves switch points in a slow and realistic fashion - much like how real world switches operate.
Does this clarify things any?
