Sn3 roadbed. NO bevel, scale 9"h and 11'w across the top. 8' bundle
Roadbed built with a prototypical 30 degree bevel. Scale 9" (3.5mm) high and 8' (1.5in) wide. This allows for a prototypical 6" beyond the ties when ballast was present and also allows for the proper dirt slope put in for drainage when it wasn't (that "eroded look" at the end of the ties).
