An ambiguous question. Lets assume you want to deliver a container to an industry track, and assuming the container is loaded into a container wagon, you don't need to downlod anything, as the ingradients to do this are buil-in the program. Since you did not specify any of the conditions of your set-up, here are the basic "ingredients": An industry track, called M.I.N. (Multiple Industry New). A piece of track going from anywhere to anywhere. Track is attached to the M.I.N. A loco and a car with the container position away from the M.I.N.. On the command bar at the lower side of the screen, issue a command : <Drive To>, <or Navigate To>. The name of the M.I.N. should the included as to where you are issuing this command. Then add <Unload> command. All this is very, very basic, so now you should see the train going to the industry track and unloading or making the container disappear. But wait, the M.I.N. should be configured to accept the container you have at the car. Is very simple and it has been covered several times on this forum. But if you need instruction, just ask. As a built-in assets, you can use a simple Multiple industry track that is pre-configured to accept Auran containers (20 or 40'), and have the wagon to carry one of these containers. Issue the commands and watch the action.
