A LOT OF TIMES the best system never surfaces in the market because existing and leading manufacturers are heavily invested in less effective systems. So unless a junior entrepreneur has backing and time we never see it. If not for Mike Wolfe would Lionel ever have detailed engines? Probably not.
Stud rail is one of these systems. I have had to look twice or thrice to see the studs.So all I see are two rails. However, it will likely never see the light unless someone is willing to take a risk and has the backing to challenge LIONEL, MTH or ATLAS. or ROSS.
