These loads are nice quality and represent excellent value for money. The loads do need a little bit filed from the edges to fit but it isn't a big job to do. The loads on the top are presented as finely graded coloured chips of your chosen ore, black for coal, rustic red for iron ore, etc. It would be great if the grades were more mixed of fine to intermediate and coarse, but I'll not knock it for what it is. I bought these initially in a bulk buy, to load up my PTA wagons, as I knew that they would sell out fast. Just as well as they didn't hang around for too long. So, it was a terrific way of getting loaded without having to touch the alcohol, having a hangover, and getting glue and little chips over the floor, LOL. What more can one say about these, other than a slightly more mixed rougher and coarser appearance .to them in future. At least it shouldn't take long to fit them and remove for the return journey without trying to force them. A useful product and with a little thought, one can glue a small piece of steel sheet underneath them to aid removing the loads from the wagons with a magnet.
