In this video from oorail.com we demonstrate how to create simple but realistic drainpipes for your OO gauge layout. The video walks you through how to quickly build a drainpipe from simple and cheap wooden BBQ skewers. As you will see from the video a small bit of flat black paint and a wooden BBQ skewer can create realistic looking drainpipes which will add depth and dimension to retaining walls and tunnel portals on your layout.
