Am I interpreting NMRA RP 12.2 correctly? NMRA RP 12.2 <http://www.nmra.org/standards/rp12_2.html> indicates that the diverging point of a S scale switch has a 58-inch radius for switches with Nos. 4, 5 or 6 frogs. Also, the curved rails between the diverging point and the frog have radii of 21, 36 and 58 inches, respectively, for these frogs.
This suggests that a No. 6 switch can handle anything in S scale, except perhaps a 4-12-2, if the switch is built to the NMRA recommended practice. (The modeler also has to consider RP 11 <http://www.nmra.org/standards/rp-11.html> on curvature and rolling stock.) I wonder about this every time we discuss the Shinohara No. 6 switch and its short curved closure rail and too tight radius. -- Bill Roberts, Receiver San Antonio & Aransas Pass Railway Co. * * * Notice to travelers * * * Coach travel on Aransas Pass trains is looked upon as a marvel of perfection by the world of transportation!
