An easily assembled pre-milled railing system having upper and lower rails supported between spaced newel posts and a plurality of balusters disposed between the upper and lower rails. The balusters have upper and lower ends with respective parallel aligned spline grooves that continuously extend across the balusters ends. The upper rail is provided with a continuous elongated spline groove extending along the bottom side thereof. The lower rail is provided with a continuous upwardly projecting spline tongue that extends therealong on the top side and penetrates the lower end spline grooves of the balusters. An elongated spline has an upper side continuously received in the upper rail spline groove and the lower side of the spline is received in the upper end spline grooves of the spaced balusters. The elongated spline is first secured to the upper end of the balusters by nailing downwardly through the spline into the upper ends of the balusters. This spline is then secured to the upper rail in the spline groove by screws which penetrate upwardly through the spline into the upper rail. The railing is uniquely illuminated with an optical light transmission rod that is illuminated from a lamp mounted within an accessible compartment within at least one of the newel posts.
