to add my tuppence worth to this
I would like to see coaches that are still around for irm to copy easily plus that have multiple livery options
the laminate and the park royal would both fit this option
but we also need proper steam heating and generating vans as well
which can easily be the BR vans and also our own 1916 brake which is a laminate base design.
in modern terms the DE Detrich stock is possibly the only one to carry a couple of liveries as the MK4 has not .
