I have been wondering for some time why my two of my Parkside open wagons have changed shape. A 16 ton mineral wagon has distinct bulges in the center of each long side and a 5 plank wagon has "sprung" all five planks at one corner. Tonight it dawned on me what has probably happened.
I have weighted each wagon to about 50 grams using "liquid lead". I just poured it in and added a dilute PVA mix which then set holding it in place. Now I know we didn't have a particularly good summer but my layout is in the loft and it does get quite hot, sometimes 35 C up there. My guess is that the lead has expanded in the heat and that is what has caused the problem.
If I am correct, I think the cure will be to make an internal box to take the lead. The box would need some room around the edges for expansion but at least the wagon sides wouldn't be taking the strain.
What do you think?
