For years I ran my N Scale oil-burning steamers around the layout. Then I realized that they never got refueled, as the pike was awash in coaling towers. Not many N Scale Oil Columns are available, but Showcase came through. You should measure your locos' height, however, because you may have to fashion a base for these little jewels to get them above loco cabs. A block of bass wood worked fine for me. You'll need more than one if you plan to provide fuel around the layout.
