I've been revamping a few areas on my N Scale layout lately and one of my projects was redoing a pair of bridge abutments. When I was first doing the scenery I simply painted the end of the foam riser gray and called it done. I finally got tired of my half-assed effort and built these wooden ones out of some craft sticks and stripwood purchased from Michael's.
I glued everything together with Tightbond wood glue and stained it with Minwax "Special Walnut," which to me looks like creosote oil, the wood preservative used by railroads. I love how the stain really brings out the grain of the wood.
