Because the wagons must run empty to the local mine and then depart full, there is no opportunity to cheat a little. Therefore, I have included spreader bars to the wagons although this has added some extra challenges when it comes to fitting coal loads.
Initially I tried a commercial product made for the Silvermaz kits I was using, but these did not allow for the spreader bars. As a result, a fair bid of cutting was necessary. This worked for a CCH load where the "hungry boards" provided some additional depth but the same process failed dismally for the LCH.
I also modified a few K truck coal loads and, again, this worked for the CCH but not the LCH.
Finally, I decided to scratch build the LCH loads using a very thin sheet of styrene as a base. In my most recent attempts, I have added some ribs for extra stiffness. Adding coal was done in stages, with first being a layer superglued to the styrene. When dry, a second and final layer was added using normal track ballasting techniques followed by a final touch up of black paint around the edges.
So now there are 13 loaded wagons ready for Port Waratah with a few more to follow.
