I'm almost certain that the photo of the 9F was taken at or near Werrington troughs, which caused me to wonder whether I have ever seen water troughs modelled. I can't think of any models which incorporated them, but I presume there must have been. Can anyone help with that query please?
Gilbert, I also cannot recall any model featuring water troughs, however, Ratio do produce a kit for them in OO so there must be a demand out there somewhere.....
