TSMRI’s “Old Line” Layout
The “Old Line” layout is HO scale; it occupies a space 22’ x 37’ and closely reflects the L&N prototype circa 1952. It is approximately 70% scenicked with over 100 structures. Like any layout, it is NOT finished – and probably never will be!
The layout is an “around the room” loop to loop with two peninsulas including the Murphy, NC branch. The Southern loop is currently used as staging; the Northern loop will be the location of a helix leading to a future upper deck which will include the line from Ducktown, TN through the Hiwassee Loop to Etowah, Tennessee.
The single track mainline is approximately 200’ in length with cork roadbed. The layout height ranges from 43” to 48” with maximum grade of 2.75%. The benchwork is open grid with foam board. Trackwork is Code 83 Flex-track from Walthers and Atlas; turnouts are a combination of Walthers, Peco and Atlas with #5’s in the yard and #6 & 8’s otherwise. Minimum radius is 30”on the mainline, 27 ¾” in Yard and staging. DCC controls are Digitrax. A painted backdrop is on 1/8” Masonite.
