This video from oorail.com explains how to build out the terrain and build a foundation for the scenery on model railway elevated track sections. In this video you will learn how to use polystyrene packaging to build terrain, solutions for building low relief inclines, tips for how to reduce the mess when cutting polystyrene, tips for keeping hillside terrain together without using glue, how to quickly clean up, how to fill in the gaps around the track supports and how to flatten the elevated track bed. What do you think of our test train? Any idea why we use this particular loco and mixed-rake of rolling stock?
