I downloaded an asset called 'Snowplough' (https://www.auran.com/TRS2004/DLS_viewasset.php?AssetID=116119 / KUID:316142:4634 ) which appeared to be a smaller snowplough- the kind that just comes up to the engine's bufferbeam rather than the large ones that are pushed by a locomotive. However, it's listed as a 'product'- I assume that means a product of an industry, like wood from a logging plant or coal from a mine. How do I apply this to a locomotive to use it?
