Shiny surfaces can spoil the realism of any model train set layout. Shiny surfaces can make model buildings and model trains look fake as though they have just come off a shop shelf.

A simple way to remove that shine is to overspray the structure or rolling stock with Dullcote (Testors #1260 clear flat lacquer overcoat). Dullcote is available at most model train hobby stores and comes in a small spray can like many other model car colors.
