Himself has been tinkering with the prototype flat wagon to try and improve its ability to stay on the rails.
The first runs at the Glasgow show suggested that the all-resin construction is a little on the light side when faced with the kind of complicated point work we have in our fiddle yards.
His idea was to fix a layer of 'liquid lead' shot on the underside of the wagon floor and I'm told initial tests suggest it is an improvement.
Were I to make a second version I think I might experiment with adding some lead shot when I pour the resin into the mould for the base of the floor which is hidden with the durbar plating.
I did consult a friend who is a doctor of chemistry to ask if mixing lead and resin was a foolish idea?
But his advice was it should be no more toxic than casting with resin already is....
