What did you do to your trains today?

While I did have moderate success with the eye coupling and wheel casts, the hook coupling failed and I even lost the one used for the mould. For my second attempt, I took one of my assembled trucks (which will have its hook back after an adequate result). I'm hoping to try and accurately reproduce the body and chassis in addition to the moving parts. If this will turn out well, it would hopefully change the way I'll build scratch built vehicles from then on. At this point, hot melt glue is the only decent material I can use for casting reproduced parts (clay doesn't have the same properties and might be a bit coarse or heavy in some areas).
