Model Railroad Academy’s Clickety and Clack (Doug and Steve) fielded a wide variety of live questions from viewers on the latest edition of Track Talk Live. Among the topics discussed are DCC (use it!), flower foam for scenery (don’t!), creating smooth transitions for inclines (cookie cutter method), making basic turnouts DCC-ready (cut gaps), replacements for worn out plastic U-joints, and many others. They also shared projects they’ve been working on since last month.
